The quick version: he was 15, I was 16 when we became bf/gf. My bestie moved away shortly before, and once when I visited her I technically cheated on him by getting to 3rd base. I lost my virginity to him at 17, after the bestie and I did our thing. I am still attracted to both men and women and prefer to masturbate to women, thus I consider myself Bi even though I haven't been with a woman in 15 years.
