I've known this girl for about 2 years and in the past 10 months or so we've went from having a normal type friendship to a friends with benefits type thing. To be honest I think she has more potential as a friend than as a f**k buddy, I think sex is getting in the way, but I don't know how to tell her "hey, I don't want to have sex with you any more, lets just be normal friends from now on". She flirts with me A LOT and I can tell what she want's to do just by the way she talks, for the past 2 months I've literally ignored every sexual advancement and tried to send her subtle clues that I'm not interested anymore, but she still doesn't get it. Now she's coming back to town next week and I already know she wants to meet up. I don't want to have sex with her again.
What to do? I'm afraid of making her feel like she's not good enough or something.
