When I started crossdressing

So when I was 15yo I started to wear my sisters pantyhose and underwear under my boy clothes. I loved the feeling. I would wear them when masterbaiting.
When I was 19 I skipped my college classes and was driving around looking for something to do. I found an adult book store. It was all down hill from that point.
Sitting in the movie theater section, an older man asked me if I was enjoying the movie? Not knowing what was going on I sat there talking to him. When he started to rub my thigh I was in a panic because he had his cock in his other hand. He moved his hand up higher to my cock. Again w/o thinking I placed my hand over his and started to rub my cock. Without a word he had my cock out and in his mouth. It felt so good I came in his mouth in a min.
Not knowing what to do I zipped my pants and started to leave. He grabbed me by the arm and asked if I was going to take care of him. Not wanting to suck his cock I started to give him a hand job till he came in my hand.
That day was the day I started to like men.
