I'm a bit shy to ask someone I know but is it normal to stop having sex in the 3rd trimester. I am 33 weeks pregnant and I just don't want sex right now. My partner is very good and has not pestered me at all. I'm just worried because I know sex is really important to a man and to a relationship. After the baby comes I won't be able to have sex for another while either That will be 3-4 months without sex. Will our relationship be okay? I am scared he will look elsewhere (even though he is not like that). I think I've read too many trashy magazines in my life where the woman is always cheated on whilst giving birth etc. Anybody else's experience would really help.
