When should you tell a guy this?

So when do you think is the right time to tell a guy that you’ve started seeing that you aren’t very sexually experienced? For reference I’m 24 (yikes I should probably have boned a few more times at this point, right?) and I’ve only slept with two guys, once with each guy. I’ve started seeing this new guy and I don’t want to make him disinterested by telling him too soon that I’m not sure of what I’m doing all the time.

Any advice helps thank you
