if you realised that while you were asleep, or DH thought you were asleep, that he was stroking your leg while masturbating next to you in bed? It probably wouldn't matter to me but our sex life is pretty much non existent; we've been married for over 25 years.
There have been many issues along the way - he has severe mental health and physical problems, it appears he was sexually abused as a child (though I'm not totally convinced on that) and sex has always been a touchy (or not touchy) subject for him but we've muddled along. Of course I'm aware he probably has a wank but it's the feeling he is doing it next to me while touching me, thinking I'm asleep. Just makes my skin crawl.
