There are some things to consider to help you stay safe and healthy when having sex.
Sexually transmitted infections (STIs)
Using condoms is the most effective way of protecting yourself from STIs. Having regular STI tests helps to keep yourself and others safe. Not all STIs give you symptoms so don’t wait until you feel unwell. See the NHS’s advice on STIs.
Some STIs have similar symptoms to Crohn’s and Colitis. If you think you may have an STI or are having symptoms of an STI, speak to a sexual health clinic. They provide tests and treatments for STIs. Find your nearest sexual health clinic:
There are many websites advertising private STI tests for a fee. But you may be able to get a free STI sent to your home. Brook has information on finding free STI tests.
Anyone can get an STI, but using condoms can help protect you. If you have Crohn’s or Colitis, there may be other factors that increase your risk of catching STIs:
- Having open, sore skin. If you are regularly wiping your bottom this can make it sore. Diarrhoea and incontinence can also irritate skin and make it sore. Help your skin heal by using warm water to wash around your bottom and pat dry with toilet paper. You can also use barrier cream to help the skin heal. See our information on diarrhoea for more tips on skincare.
- Some medicines can lead to vaginal dryness which can increase your risk of cuts and tears during sex. You can lower this risk by using lubricant.
- If you use condoms, be aware that lotions or oil-based creams can make condoms weaker and more likely to break. If you are using creams, ointments, or any medicines in or around your genitals or bottom (such as barrier creams) ask your IBD team or pharmacist for further advice.
Herpes
Herpes Simplex Virus (HSV) commonly known as herpes, is a common infection. There are two main types – oral (cold sores) and anogenital (around the bottom and genitals). In England, around 1 in 5 adults have a genital herpes infection by the age of 25.
Herpes spreads easily, mainly through skin to skin contact. You are most infectious when you have symptoms, such as blisters and sores. But Herpes can still be infectious even if you don’t have symptoms yet. Once you’ve been infected symptoms can come back – this is called an outbreak.
If you are taking immunosuppressant medicines your risk of having an outbreak is higher. However, there are antiviral treatments available to help with symptoms. If you’re having lots of outbreaks your doctor may recommend taking daily antivirals to prevent outbreaks.
If your partner has genital herpes, help protect yourself by avoiding sexual contact until they are well again and their symptoms and sores have gone. Using condoms can help, but cannot protect you completely.
The Herpes Viruses Association has more detailed information on what herpes is and how to manage it.
Thrush (candidiasis)
Thrush is a yeast infection you can get on and around your genitals. Thrush is not an STI. It can make your genitals feel very itchy and sore. It can make having sex uncomfortable. Having a weakened immune system or taking antibiotics can increase your risk of developing thrush. If you think you have thrush, speak to your GP, IBD team or local sexual health clinic. There are over-the-counter medicines for thrush, but they may interact with your Crohn’s or Colitis medicines. Check with your IBD team or pharmacist before taking an over-the-counter medicine for thrush.
Mpox
Mpox, previously known as monkeypox, is a rare infection. Mpox is spread by physical contact and coughs or sneezes. Mpox is usually found in west and central Africa, but people have also been diagnosed in the UK. Mpox can affect anyone, but most cases in the UK have been in men who have sex with men.
Men who have sex with men can get a vaccine to help protect against infection. It is safe to have the Mpox vaccine if you are taking an immunosuppressant. The NHS has more information on Mpox, including how to find a vaccination site near you.
Human Papillomavirus (HPV)
Human Papilloma virus (HPV) is a common virus found on the skin. Some strains of HPV can cause genital warts or certain cancers. HPV is spread by sexual contact and is more common in sexually active people.
The HPV vaccine is offered to all teenagers aged 12 and 13. This helps to protect them against certain cancers. There’s also a catch-up programme for people aged under 25. And a separate programme for men who have sex with men. It is safe to have the HPV vaccine if you are taking an immunosuppressant.
The NHS website has more on the HPV vaccine.
Human Immunodeficiency Virus (HIV)
We do not know much about the relationship between HIV and Crohn’s or Colitis. Some evidence suggests HIV infection may result in milder symptoms of Crohn’s or Colitis. But more research and evidence is needed to know for sure. If you have HIV and Crohn’s or Colitis it’s important to get treatment for both conditions.
Being HIV positive might mean you cannot take some medicines for Crohn’s or Colitis. Let your IBD team know your HIV status to make sure you’re on the right treatment for you.
Taking PrEP
PrEP (pre-exposure prophylaxis) is a medicine to stop you catching HIV. PrEP is free in the UK for people who are at greater risk of getting HIV, such as men who have sex with men. See Terrence Higgins Trust, or speak to your local sexual health clinic for more information on what PrEP is and how to access it.
None of the common medicines used to treat Crohn’s and Colitis have major interactions with the medicines used in PrEP. But it’s always best to check with your IBD team or pharmacist before taking any new medicines.
I’m HIV positive – do I have to tell my IBD team?
You do not have to tell other healthcare professionals, such as your GP or IBD team, about your HIV (or any other STI) status. You may feel that you want to keep this information private. However, your IBD team may need to carry out HIV screening before starting some medicines. This is to make sure you aren’t taking a medicine that could be harmful to you. See Terrence Higgins Trust for more information.
