I'm having a hard time understanding something.

I've dated a unicorn pretty much for a year 10/10. After having sex and doing different things with her I find a hard time enjoying or carrying about sex with anyone below 9.

What the fuck does that mean? Lol

Don't get me wrong I still fuck with the other chicks but I just don't enjoy it or put any emotion into it

I recently started FWB with this chick that has a boyfriend and I think she's alright decent body fun company and interesting in general but she's 6-7/10 and it's like I could care less if we fuck or not even though I find it hot that she's sneaking around with me while in relationship.

and no I'm not still stuck on my ex, no contact / blocked don't even wonder about her anymore. Been 8 months.

So am I overthinking it? Or is it just because I've magically got standards now?

Thank you.
