Yes it happens to me too! I also get cramps during, and it's starting to get to the point that I have to stop ); I've read that orgasms cause mild contractions, but you should check with your Dr to make sure everything is ok with your cervix just in case.
Yes I do.. it can cause contractions. Though it may not put you into labor it still causes contractions (minor in most cases).. that's why when people are high risk sometimes they get dr orders no sex
