When I was younger I had sex with an older guy. He didn't take advanatge or anything like that. I was quite curious and interested. The first time we got naked together we sucked a little bit on each other's erection, and then he slicked his erection with some lube and pushed it into my butt. It was unbelievably stimulating that I started ejaculating after only a minute. After that experience, I was so hooked on male sex, even though I have never consdiered myself to be gay.
