AIBU to be sick of it?

[talkthetruth]

I have a close friend. I am married. She is not. I have kids. She does not.

She constantly talks to me about her sex life, now and in the past. I feel like she is trying to prove something. She doesn't realise how insecure and desperate she sounds.
I don't feel any need to talk about my sex life. I want to tell her that I am not in any way interested in who she has or has had sex with, or how it rated on a scale of 1 to 100.
Am I being a bad friend? I think I must but she is driving me crazy.

Try to divert the conversation.

In my experience these things fade away and the person who did all the talking about their intimate life feels embarrassed about it after a while.

Thanks Rebecca. She wasn't like this historically. I find it quite revolting listening to all the gory detail. I can't understand why somebody wants to share that. I feel embarrassed for her to be perfectly honest.
