I have been with my husband for 5 years and we still have sex nearly everyday and he takes no more 20 minutes. Sometimes I wonder if he be thinking about other women while having sex with me. Any advice??
No not usually. It is very hard to imagine someone else during sex for a man. It would take a lot of effort especially everyday. Most men do their imagining when they masturbate. Try talking to him, but instead of asking him if he is imagining someone else, try to ask him what his fantasies are. Maybe tell him there is something you would like for him to do, that way he feels comfortable to tell you. He might like for you to dress up or role play or what have you. Try to be understanding and trusting so he feels comfortable sharing that side of himself with you. Remember to do it in a sly way so that he doesn't think your trying to trick him. Luck.
I hope he's not thinking of anyne else. But hey, to spice things up, be another woman! Role play! Surprise him one night and dress up as a nurse, or a police officer or a school girl, or wonder woman! It will be a lot of fun for you too.
