Just a few thoughts here from a male perspective;
Some PPs have given good advice. I’d say this breaks down into two parts, things you have to do and things you could do.
Things you have to do are literally nothing. You don’t have to have sex with this bloke and if you decide you want to have sex with him you don’t have to tell him anything. It’s your private information, it’s your business, end of.
On to what you could do if you do decide you want to have sex. I would highly recommend telling him, so you both, but especially you, have a better experience. Given the little info you provided I guess he likes you a lot and I’d be astounded and amazed if he was put off by you being a virgin if that is what is worrying you. I assume you have no idea how many previous partners he’s had, if any. I'd usually say it was a little weird that this hasn't already come up in conversation, but we're living in crazy times!
Looking at it from a male perspective I would definitely change my approach to sex if my partner said she was a virgin. Take things much slower, be more gentle, have different expectations of what might happen and be prepared to guide (assuming he’s had experience) and stop and start when you needed to.
Also maybe the first time you share a bed you don’t have full sex, there are plenty of other fun ways to start things more slowly and maybe you try that? Or even something like having a shower together and using that to explore each others bodies. Obviously, that would involve getting naked so maybe not just yet for you!
But as others have said do what you want and feel comfortable with.
Sex can be (usually is for me at least!) an amazing experience that will bring you much closer together and form a real bond (obviously not guaranteed!), so long as both of you are comfortable with what is happening. Good luck with whatever you decide OP!
