So as a guy who isn't in any way physically imposing (I'm 5' 6" and about 110 lbs), I find myself being complimented by women, but in an almost backhanded way. I can make girls laugh, go out to lunch with them one-on-one, dance with them at a party, but I never seem to be "boyfriend" or "one night stand" material to them. I've been told I act/look adorable and cute way too many times that I'd like, and I'm always striving to change that.

Should I look to hit the gym and pack on the muscle giving the impression that I'm not a skinny wimp? Or should I change my personality a bit and stop acting in this cute, adorable way that I'm accustomed to being?

TL;DR: Comfortable with the way I look, but done with being the cutesy guy that girls like to hug/cuddle with and nothing more. How I do to fix this?
