Now I must be honest here normally weight is a HUGE TURN OFF for me………
Women often have a misconception that most guys like skinny girls.
A lot of guys, in fact, prefer curvy women who have meat on them as it is a more feminine look.
Honestly, you do look overweight (but not obese, as you said), but that's not enough for it to be a dealbreaker.
The main thing that matters is that a person has an attractive face, which you seem to have.
Taking care of yourself by being active and healthy is far sexier than sitting around getting bigger and bigger and questioning why the men you desire don't desire you.
Maybe find a larger guy and start a work-out routine together for motivation. Things like – Over all proportions, Attractiveness, Femininity, Elegance, Grace, Care of her appearance………the list goes on.
I don't see why women are so obsessed with looking as flat-bodied as a 10-year old boy.
Ultimately, as cliche as it sounds, your personality will matter more, including your humor, wit and capability of holding an intellectual conversation. I have learned in my 30's that more men than not like a woman with curves. OP, men like curvy hips& butts and it's not really relevant to your size as even thin girls can have curvy hips& a bubbly butt.
I could hardly find clothing there that fit me and when I did, they were usually XL's.
