Believe it or not, until I was 33, I only had four (still believed in "saving myself" for someone I truly cared about). When I was 35, I became disillusioned and discovered just how easy it is to get it in strip joints. Since then, I'd say it was between thirty and forty.
Most amazing-one night stand with this barely legal hottie in San Francisco. We did it for eight straight hours. Countless orgasms and complaints from the neighbors (we were in a hotel).
