My boyfriend and I have been having sex regularly for a while now. It's been pretty good- the only two problems is that one, our friend, who is the brother of our mutual best friend (his sister), refuses to keep his opinions to himself. Secondly, both of them are acting like we're abandoning them. For the sake of convenience, I'll refer to the sister as B and the brother as L.

Unfortunately, its been like this since the very start. Both of them decided from the start that they were entitled to know about our sex life and to make comments about it. B was furious that I didn't immediately tell her the first time my boyfriend and I had sex. (I didn't say anything at the time because she was stressed and busy, and quite frankly, it's none of her business anyway. I only said anything because she mentioned that she said she'd be mad if I didn't tell her when we had sex. She was mad anyway.) She immediately began to act hurt and betrayed, playing the victim and acting as if I didn't trust or caring about her because I didn't immediately tell her. She guilt tripped me for a good while. This was the first and only time I've seen my boyfriend mad at B.

Naturally, it had to get worse from there. B immediately decided that L had to know, so she immediately told him without asking me or my boyfriend if that was okay, excusing her actions by saying that we never told her /not/ to tell him. L immediately made his opinions known, first by calling my boyfriend and I stupid, then telling us to not say he didn't warn us after I told him to shut up multiple times and that it was none of his business, with B chiming in and telling him to stop. Of course, he didn't actually shut up; he decided it was a great topic to make jokes about, saying that he couldn't get the perverted images out of his head and it was so hard to not make inappropriate jokes. We got into another fight, with me telling him he was being insensitive and him saying that I was overreacting and him essentially being confused as to why I was even upset.

That conversation happened about a month ago. Now, it's gotten a bit better. B's stopped mentioning it entirely and has gotten on L's case for still making jokes about it. However, both of them think that my boyfriend and I only care about each other, complaining that we never talk to them or want to hang out, (which is completely untrue) and the fact that we're having sex has only soldified that. Every Saturday, (which is the only day my boyfriend and I see each other) L always has to make some sort of comment about our sex life, followed by B reprimanding him.

I'm not mad at B anymore, but L's refusal to stop making comments, despite the fact I've told him multiple times that it was none of his business and I didn't want him talking about it. My boyfriend and I can't exactly cut him out of our lives, because he's B's brother and he's a decent friend when he's not making comments about our sex life. Both of them are also maintaining the opinion that they're being ignored, especially when Saturday rolls around.

Does anyone have any advice for dealing with this situation? I really just want him to stop making comments and I want both of them to stop acting like we've left them behind.
