My firsts were good personally.
First time I got head was mutual, in high school, over 12 years ago. (Not where you think it's going) Went to an all boys school, student at our all girls sister school I was friends with doing musicals/plays came out to me as trans, transitioned years later. I was their beard initially but we fooled around a few times.
First time I got laid was at 18 with my sister's friend during a trip. They were 12 or 13 years older. Everybody got drunk, we went to bed together. Both woke up in the morning and got busy, dated for a few years after.
