I joined this site since my bf is an owner of a very large penis, its 9 and pretty thick (havent measured) but we have had no problems having sex. However, recently we stopped using condoms since we moved in together and it looks like he will be the one (we both are tested and CLEAN). He cums a lot! which is awesome since its such a turn on to be with such a virile guy, but I noticed that when we are making love and he cums in me, it feels like a huge amount of semen is put inside me. But I only see a small amount actually coming out of me when I go to the bathroom. Is my body absorbing his semen? I know the anal canal functions to absorb water and other nutrients before expelling matter from the body. Also my friend says that he was allergic to one of his ex-boyfriends cum, eventually breaking them up? Any info on this??
