I get itchy balls after having sex with my GF. We have been togther for over one year and it has only started happening recently. It has been just under 24 hours now since we last had sex and they are still itchy.

There are slight red marks but nothing obvious, that could just be from the scratching.

The last time this happened it lasted about 24-48 hours.

Any ideas?

Oh I'm 31

Some women have a natural higher level of acidity in there vagina. If you are both monogamous and you are sure that you both do not have anything then I think this could be the problem. Also if you are trying any new birth control, lube, or something of that nature. I hope this helps.
