Secret Not A Virgin

It feels good & equally bad to share this so here we go. I’ve been engaged now for a year with my long term boyfriend. I’m 19 & we’ve been together since we were 15. We are both virgins & plan to have sex on our wedding night. We are quite old fashioned you could guess. Only I’m not a virgin. Unbeknownst to him I had sex quite a few times since I was 15. I feel a bit ashamed to tell him so I’ve kept it secret. The only issue now is it could all come out. I’ve been fucking the bouncer at the local bar near where we live & to be honest I don’t want to stop. It’s gotten to the point where I think I might just call it all off. In my defence I’m young & naive lol. It all started when i went to my first night club at 15 & the bouncer took me home in his words black kryptonite ha. What should i do….
