How can I move on after oversharing my sex and counseling issues?

Sounds awful. But I was getting counseling. And I was so used to taking about it, I just spilled my guts to colleagues. Then I discovered all my old friends were laughing at me. That's a few years ago but it's still mortifying

The issue was that I felt too guilty to actually have sex with a girl. Embarrassing.
