How do I tell my current bf that the first person I did it with was a girl? I like men but I’m not so used to touching their thing down there and i know he knows that. I’m just not sure if I should say anything about my past though.. Should I?

Why do you feel unsure about telling him? If you’re engaging in sexual activity with your partner, one of the first steps is to tell the other person your sexual history. I don’t mean every detail of it, just the bare bones. How many, have you been tested, etc. Just tell him you haven’t had sex with a guy before and that way you can hold off for a little while before explaining that you’ve been with a girl before. I think you should tell him, but if you want to wait on it so you get to know him better before revealing that, then wait.
