Just Tired

[TiredTN]

So I've read several threads about sex in marriage, it sounds like some people go years without it and others are doing it 2-3 times a week (some more). What is normal? My marriage is definitely starved (I think). We have been at about 8-10 times a year for years. And it's mostly bad sex. The last time we had sex it was so bad I would have rather taken care of business myself. She admits she is just "checking (me) off on a list" of things to do. There is little to no foreplay, no conversation afterwards, no nothing. Just, "let's get this done." What is normal for sex in terms of frequency? What is normal in terms of a "quickie" with no foreplay (or afterplay) vs "real" sex?
