Straight curious but feel uneasy

Hello there to whoever reads this

So I’m currently 19. I’ve been curious as to exploring more and experimenting more w guys and trans people. When I talk to them and exchange pics and things I enjoy it. I do want to meet up with them and actually hu but for some reason I feel like I’d feel regret or guilt for doing so.

I’m a straight guy and see myself as that. But has anyone ever been in the same boat as myself. Where they know they’d have fun and want to follow through. But also think they would feel guilt and possible regret for doing it?

How did you deal with it. Was it a thing where you just pushed through and hooked up or what?
