<human>: I'm not very good at expressing my point so please bare with me. I'll do my best here.

Brief backstory:
We have had sexual tension in our friendship from the start 5 years ago. We have had sex a few times and each time it has almost torn our friendship apart. The first time we didn't speak for a few years afterwards. We weren't as close back then but still.

We reconnected over a year ago and have become super close. As close as you can get without dating. She is a very sexual girl and has recently introduced me to the bdsm world (which it turns out I'm in to). I'll admit I have had feelings for her but I know she doesn't share the same for me. I have been completely fine with being the best friend while she was in her last relationship. Now that they are broken up and she is able to "entertain" the men that have been knocking at the door. I find I am incredibly jealous of them. She tells me everything, shows me the pics and the bruises she gets from them (don't worry they are not abusive bruises, they are play bruises). 

I cherish her friendship and don't want to loose it. But I can't help but get distant or short with her when she brings these things up. I don't want to know because I find myself wishing it was me. I was able to be a good friend while she was with her now ex because I knew there was no chance for me and she didn't tell me about their sex life as much. I feel like I am betraying her by being jealous. I feel like if I could ask her to not tell me these things I would be able to manage better. I know I'll never be completely free of the jealousy but if I don't see the results or hear the stories it will be so much easier. I'm also worried that if she finds out I still have feeling for her she will just end the friendship.

Is there a way to ask this of her and keep our friendship?

Can you give me the gist of the text in a nutshell?
<bot>: Jealous of my best friend having sex and not me/with me. How can I talk to her about it?
