No it is not harmful to have them back to back...... Depending on how far along you are.. This will come in great handy when your body is ready to deliver your little one because sex can actually soften the cervix and make you go into labor... But don't worry about that now... If your body is NOT ready, it won't happen.. So ENJOY ALL THE ORGASMS YOU WANT!!! *LOL*
What?? Orgasms?? Like when you have sex? My goodness I wish I had orgasms back to back to back.... I really have no Idea ... Are you pregnant?? I know when I was pregnant I couldn't have sex because if i had an orgasm my stomach would get so rock hard and very uncomfortable...so I am guessing if you feel faint after one maybe it's not so good....but I don't know
