My girlfriend and I have been practicing safe sex for almost a year and now she wants to be open to anal intercourse. Honestly, I really don’t mind that we do.Now, I know that pregnancy is impossible when resorting to anal intercourse but what actually happens. Where does the semen go? Is the semen that is deposited inside her detrimental to her health? Can I ejaculate while I have anal intercourse? Will this affect her, physically? Will she be sore? Help!!
