Not quite sure what to think or feel. We were having sex, I was on top for some of it, trying to be engaged and asking what he wanted (he is very vanilla, won't ever share any fantasies, claiming not to have them). He stopped, which was fine saying he was tired. Went to bathroom and shower was on so I assumed he was in it. I was suddenly desperate for a pee so knocked and ran in whilst apologising, he was in there with his phone wanking to porn.
I've recently lost a considerable amount of weight (4.5 stone but slowly over 10 months) and am a bit conscious of slightly droopier breasts (but not dreadful). Is this normal? Has he just gone off me?
