Yes, for me -- but more vagina than anything else. Some girls have really nice-smelling vaginas and some go all the way to rancid. Some are all hairy down there and some are waxed bare. Some get extremely wet and some not so wet. Some are tighter and some not as tight. Some can contract and grip and some can't control the muscles there so well.
It's mostly vaginas I compared most between girls. Then it's like the rest of the body is secondary. Anyway, an excellent vagina is really top priority for me.
My ex had dated a lot prettier, toned and thinner girls than me as well. I don't think that he thinks she's better than you because he must have loved you for who you were and accepted what you look like. I personally think that you should not worry about his current girlfriend.
I think you should focus on yourself and finding someone better for yourself!! Rather than tormenting yourself about what he's thinking about how much better or how much worse he thinks of you in comparison to his new girlfriend. ... Just move on and be happy!! A happy person is always envied. 😁😛!!
