There is nothing in me that girls might find attractive. So how do I stop myself from thinking about girls?

I'm not rich or have a lot of money. Just a guy with average amount of money. I'm not sexy, I'm just average or ugly, not sure which one. I'm not tall, only 5'8. I'm not smart at all but I still try real hard in college. Doesn't help much though because I'm kinda dumb. I'm not muscular or really strong since I don't get the time at all to hit the gym since it takes me ages to finish college work due to me being dumb. I can go on and on about my negativities. Anyways I'm the complete opposite of what a man is supposed to be in the eyes of a woman. This is why I'm a 24 year old guy who still hasn't even kissed a girl yet, forget being virgin. Unless you count being sexually molested at the age of 7 few times by a guy before finally moving as losing it. But yeah, there is nothing in me at all that would want any girl to like me. I posted questions here before and people suggested me to join dating sites and I did. Well it's been a while since I've joined but not a single girl on that site replies back to me. Not even one. So yeah, since I saw that as my last option and failed to find a girl that was attracted to me, how can I biologically stop thinking about women?? Is there any way or any medication I can take which will completely stop me from thinking about women? Or no? Should I castrate myself? That's too painful though so I need a safe way to stop myself from thinking about girls because it's just too depressing.
