Ugh.
@Gamisch is correct. You are putting the cart before the horse. Hit the gym, establish some workout habits, see what you can do to improve your work/financial prospects....those things are more important than cruising for chicks right now, and as you body and prospects improve, you'll gain some confidence, which you need.
My husband is not a good comparator for you, spectrum or not. He has serious Chad looks, makes 6 figures at a Fortune 500 company, is a semi pro athlete, and has a lean, trim & sexy physique. He looks amazing naked, and is handsome enough and photogenic enough he could model professionally. He has a eclectic LA rock star style and was in the music business in years past. He has an incredible voice and an entralling stage presence/persona.
As a result, women approach him constantly and give him IOIs constantly. He misses some of the cues, secondary to his difficulty with social calibration, but women will walk right up & try to pick him up. At times even with me sitting right there. They ask who he is, what band is he in, etc., etc., etc., He usually just stares at them for a moment...then he announces "I'm with my wife", and turns his back on them or shoos them away. He comes off very arrogant and aloof, even rude to them, and tends to make them look & feel foolish. Some of this is unintentional, some of it isn't.
He's had many sexual escapades because of his looks over the years, but has been, up until this point, a serial monogamist in relationships. Basically girls want him sexually because of his looks and badboy attitude, which is partially attributable to his condition, but he's over hook up culture & sees little value to it.
You are nowhere near his league looks wise. And that is the number 1 thing women sexually select on: looks and physique. He has both and also a killer smile.
He is pretty good at initial flirting because he's had so much practice thanks to women approaching him. That's also why he struggles in LTRs because has not been required to modify his behavior in the initial stages. He is direct and a "bold move" guy. Again, partially but not wholly attributable to the spectrum.
Some guys have less looks but on point physique.
Hit the gym for crying out loud.
