I ended two friendships a couple of years ago because of this. One was a friend (female) from university, who got into the habit of always asking me VERY intimate things to which I had, at no time, allowed her to talk about. Even worse, she got into that gay stereotypical thing - so that, everytime she would text me and I would answer only later (because, God forbid, I could be watching a movie, working out, eating), she would return like "what were you doing, naughty boy? tell me everything!". I got fed up with such attitude.
The other one was a guy I met through Manhunt. He seemed to be a nice guy, but had certain "creeds" towards gay behaviours that weren't same as mine, but he would never even consider talking about it - he was always right, I was wrong, even though I had been going out with men more than a decade before him (he was married to a woman, then divorced…). At some point I also got tired of not being able to talk about certain stuff because I knew I'd be preached. Then it was over.
And I must say: I miss nothing about both of them. Nothing.
