I keep hearing "I want a freak in bed," "Act like a porn star," etc. It's great if the Mr. & Mrs. want to swing from the rafters (and if both are into that every time, great). But the Mrs. shouldn't be expected to be Linda Lovelace 4-5 times a week, especially if that's not what SHE wants. Gentlemen, it's O.K. to satisfy her needs and fantasies once in awhile. Sex can be a form of communication between two people. If it is all about fantasy and porn, then it really doesn't matter who's in bed with you, does it? The Mrs. doesn't always like to feel that way. Compromise, and don't go to bed with these porn star expectations EVERY time. She'll feel like a failure or disappointment, and will be a lot less interested in having sex with you.
I once told my husband I never wanted to feel as if I ignored the housework, didn't make dinner and put the kids to bed filthy, he would still be happy so long as I put out like a prostitute 4-5 times a week. In other words, when you complement or thank her, be sincere about it - don't use it as a means just to get laid.
By the way, in couples counseling, we were warned off porn, for many of the reasons I allude to. Creates unreasonable expectations, depersonalizes sex and your partner, and skews your view of what sex should be. Get addicted, which is common, and you spend way too much time in a fantasy land and not in reality with your spouse.
