When was the first time?

Guys or girls. When and with who was your first sexual encounter. Doesn't have to be full on sex. Could just be the first time you realized something more was going on. Mine was at my friends pool party. Her d@d was really getting to know me under the water. Touchy feely turned into him taking his hard cock out putting it between my legs. He eventually worked it under my bathing suit bottoms and had it pressed against my ass hole and pussy.
