Sorry, didn't know that

Your comment just happened to sound alot like my ex-husband...he used to "threaten" me all the time if I didn't "cater" to him whenever he wanted. I never proved that he cheated, but considering he moved in with his now current wife while we were still in counseling told me pretty much all I needed to know. I could care less what political party someone who cheats is affiliated with, it is wrong plain and simple.
That said, no it is not right for one half of the marriage to withhold from the other, in sex, or any other facet of marriage. In fact it is unbiblical to do so. (Obviously if there are medical reasons, etc. that is a different situation entirely) but you take a vow of "for better or worse" and sometimes you get the "worse", but it does not give you carte blanche to go out and defile your marriage.
Luckily I got it right the second time around, and now I guess you could say I'm right there with ya

DH has said more than once that our roles are reversed in that aspect
Just for the record, after being cheated on in the past, I doubt there is anything in the world that DH could do to me to ever make me go down that road. Even during my first marriage which was abusive on several levels, I would never have done that.
