That's what happened to me too. When i was 14 i say interracial porn for the first time so i had to masturbate for the first time as well. So i had my first of many orgasms to Black men with white women, my penis only responded to that interracial sex for at least three years, i would masturbate to that XXX magazine and would even put my legs over my head laying on my back so i could cum in my own mouth. I only had sex for the first time when i was 19 and my best friends girlfriend took my virginity. over the years i tried to get women i dated to try a Black man for me but they never would. One woman i dated and i watched a lot of interracial porn because i wanted her to try a Black man for me but she got me interested in try a Black cock instead, she told me i might be bisexual and i should try letting a Black man fuck me too, she kept encouraging me until i found a Black man with 8 inches and he was the one who took my cherry. I called her right after he left and told her all about it and she told me she knew i was bisexual even if i couldn't tell myself. I had to admit to her that it was the best sex i ever had and she totally understood that and was happy for me. I feel crazy for even saying this.
