So whenever I have an intimate relationship with a girl I like, feel comfortable with and I find her to be around a 6/7 out of 10 (rating), I have no problems in bed, I can easily go 30 minutes and have the best sex of my life. The problem is whenever I get intimate with girls who have nice "features" about them and that's usually just casual hookups.

I never got beautiful girls until I started leveling up in life and I'm still quite young, so these types of women are new to me. I can't seem to control myself or get relaxed and I finish in 30 seconds of penetration. I think that I'm still putting them on a pedestal in my mind, but these are the types of girls I would dream of getting with when I was a loser. So what is the problem here?

Thanks for all the answers in advance.
