I have some concerns about both oral and anal sex. I’ve heard it’s possible for a woman to be allergic to the ejaculate of her partner.
Are there any other possible negative (or otherwise) side effects to the ejaculate having contact with a partner’s body?
Are there any possible dangers/negative side effects to my girlfriend swallowing my ejaculate? She always does, but apart from loving the act, I personally worry that there might be a chance of it harming her!
My partner and I would very much like to try this but I want to ensure that she is safe from any possible problems/complications.
Yes, it is true that very occasionally a woman is allergic to her partner's Symptoms are soreness, redness and swelling of the sex organs. But I know of no other ill effects from contact with seminal fluid.
Your next question is about fellatio. This is harmless, unless either party is carrying a sex infection. But it is now (2012) thought that oral sex can pass on human papilloma virus (HPV).
In the rare instance of a woman being allergic to her man's sperm, fellatio would probably cause swelling, soreness and redness in the throat.
Next, you ask about anal sex. We don't really recommend this - but there's no doubt that these days a lot of couples happily practise it – and that it has become much more popular in the last few years.
- passing on of infection (if one of you has one).
- damage to the woman's anus (especially if you're rough).
- spread of germs from anus to vagina (if you have vaginal sex immediately afterwards).
- possible urinary infection in the man (very uncommon).
- possible transfer of HPV (see above), which may be a cause of rectal cancers.
