Pounds Tech Grade

I'm a male, hetero virgin. I used to be fat. I lost some weight and now girls like my looks but think I'm weird. When I was in the 6th grade I was falsely accused of sexual harrassment, and as a result I avoided doing anything that could even possibly be seen as flirtatious for years and years. This developed into a full-blown phobia at least 8 years ago.
I didn't have any female friends in high school, and then went to a tech school where the male:female ratio was 3:1. Then I gained a lot of weight and dropped out because of depression related to this issue. I finally managed to lose over 70 pounds and get to the point where girls find me attractive again, but I feel like a bleeding child swimming in a pool of sharks when it comes to male-female relations. This has poisoned my whole life, literally.
