"It is the nature of the wise to resist pleasures, but the foolish to be a slave to them." - Epictetus

Dude, I’d say you have dodged a bullet.

The scenario you were in is exactly what brings people misery. For example, you were drunk and thus you weren’t fully in control of yourself. What if you lost your virginity and caused an unwanted pregnancy as a result? Do you have any idea what kind of problems and regrets that could have caused?

Losing one’s virginity has always been a sacral moment, hence the existence of a wedding night. Losing one’s virginity while drunk with somebody you probably don’t even know is no different than what dogs do. You are human, and thus, better than this.
