I've been married for 13yrs, every time we have sex it's like i'm a virgin again. it's uncomfortable & tight for 2mins then back to enjoyable. why?

New horizons: Although early menopause is a possibility I suggest the following: spend at least 20-30 minutes on extended foreplay until you feel lubrication, try sensual massage, aromatherpy, aqueous based lubicants, music, adult toys or videos. Remember that "outercourse is more important than intercourse" and-always communicate to your partner what feels good- your weekend Rx-enjoy. GYN if not improved.
