Problems with oral and anal sex

Well, I’m glad that our advice has helped you defeat premature ejaculation.

Yes, it is true that very occasionally a woman is allergic to her partner's semen. 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 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.

1. passing on of infection (if one of you has one).
2. damage to the woman's anus (especially if you're rough).
3. spread of germs from anus to vagina (if you have vaginal sex immediately afterwards).
4. possible urinary infection in the man (very uncommon).
