I married too young to what turned out to be a useless man. He flatly refused to give oral sex - despite insisting on receiving it, very little in the way of kissing or affection and the sex I presume isn't great from what I read elsewhere. I was a virgin when I married so I have no comparisons. My twin sister, we're not identical, is married to one of lifes good guys. She talks of the love making and the oral that she almost passes out from and the unselfish nature. I'm not bitter, I love her more than anyone, but despite knowing about my crappy sex life, she throws it into conversations. I'm actually leering at my bro-in-law when I see him now, as I know he does all the things I've never experienced which is just weird. Am I being unreasonable to mention it that the comments hurt me? Please understand that I am happy that she's happy. I just don't know how to approach it or if I even should.
