Learning social skills is equally possible. Many, many books and classes are dedicated on the subject.

Except if you are aspie, those will both take enormous effort and feel so insincere that you will drop them past the initial acquaintance, if you manage that effort. Which is the point where you are most likely done for the same reason - people don't like insincere romantic partners.

Those non-physical aspects of attractiveness for some of us are not optional.

And mind that I do have good looks and even hobbies that may occasionally seem interesting for others, and cultural context ; all the most beautiful girls I've met where I attended social events would try to get romantic by their own initiative when I was someone new for them. Some would even say I have beautiful emotions, and in general characterize me as a good human, even later (when they thought I don't hear, in person they'd plainly ignore me). You know why every such spontaneous moment failed?

Again, because of simply being aspie - ashamed of being too weak (dropping hobbies, easily getting tired, too emotional, headaches, tired eyes, already feeling dirty in the middle of the day) to be good for a girl, ashamed of being stupid (that's purely anxiety, one can't look into her skull and tell if she cares, but it exists), ashamed of being insincere because looking into her eyes is a conscious effort, so I'm pretending I'm someone I'm not, and also petrified, because I don't know what to say. And previous wounds.

These comments terribly reduce the field of possibilities which would be the reason for such people not having romantic successes, OK?

The only correct answer is therapy. Preferably the therapist should be a woman too.
