TLDR: I'm a magnet for fat girls, thin girls hate me. Why?

Body:

I have 46 "notches", only a few of whom I was actually attracted to. The thin ones never stick around long, and my usual pattern goes like this: strike out hundreds of times with thin girls, meet a fattie online or at some social event, rationalize it to myself as a "slumpbuster"/"staying in practice", fuck her (almost always under the influence of large amounts of alcohol and/or other drugs), feel ashamed of myself afterward and vow not to settle anymore, ignore the fattie when she tries to see me again. Repeat.

I'm a magnet for fat women and they pursue me aggressively. It happens so often that it's become a running joke among my friends. I was at a 4th of July party last weekend and in separate incidents, 2 fatties started conversations with me and then insisted on giving me their numbers (I allowed them to put their numbers in my phone to avoid a scene, then deleted them). All the thin women at the party blew me off.

I was at a wedding reception a couple weeks ago where 3 fatties were throwing themselves at me. I got frustrated and drunk, snuck out a side door and went back to my hotel room early, 15 minutes later one of the fatties who was staying on the same floor knocked on my door. I fucked her but was so angry at myself I couldn't orgasm. Afterward I had to sneak her out because I was ashamed of how disgusting she was and didn't want anyone in the wedding party to see.

I cannot seem to get the interest of thin women no matter what I do. I've been on literally hundreds of dates with thin women; most of the dates seem to go well, then I never hear from them again. I have profiles on OKC, POF and Tinder. I talk to thin women at bars, clubs and social events. I've only tried day game once; I tried talking to a thin girl on the subway who I thought was making eye contact with me, she flipped out and made a scene which embarrassed me and made me too afraid to do it again.

This pattern is unsustainable because it's killing my confidence and I'm starting to become afraid of thin women because I've failed with them so much and the incident on the subway. I'm also paranoid one of these fatties will get pissed I'm ignoring her and hit me with a false rape accusation. I'm about to turn 30 and the fact that I've gone through almost my entire youth mired in sexual frustration is incredibly depressing and demotivating.

I would understand if I was some kind of neckbeard troll, but the bizarre thing is on paper my SMV should be sufficient to at least consistently attract 7s. I know what I'm doing in the gym (1365 powerlifting total, 100 full burpees in under 8 minutes), low body fat, I'm white and above average height, I dress better when I go out than most guys but nothing over the top (usually nice shoes/jeans/shirt + blazer), I'm introverted because I was extremely isolated growing up but I think my conversational skills are pretty good after so many dates.

It's like I'm somehow sending out some kind of unconscious signal to fatties to be attracted to me, and thin women to hate me. How do I figure out what I'm doing wrong?
