Hi Animenerd. Love the username...lol kindred soul here.

Firstly, don't immediately assume it's all you, as that's unfair to yourself. There's nothing at all wrong with being a little thick. Not everyone finds "super skinny" to be mandatory for sexual attraction...Marilyn Monroe, as a prominent example, was far from "super skinny." The whole "skinny = sexy" thing is resultant of a gross saturation in advertising and societal perception on what represents one percent (if I'm recalling that statistic correctly) of the population. My point is be happy with who you are, and don't jump to conclusions.

As far as he goes, there could be a myriad of reasons...does he work late/strenuous job? Is he timid or shy? Masturbate a lot? He could simply have a lower libido than you, which isn't an "abnormality" or anything...just him being him. That all said, have you spoken at length about your sex life with him? A little conversation in that regard could go a long way in discovering what it is that determines your frequency, and possibly compromise for increasing it.

I hope things improve soon, and I wish you all my best.

Hugs,
Harley
