Should I tell a guy that he’s my first kiss?

Brie

I’m 17 and I’ve never been kissed, had a boyfriend, gone on a date, or anything. If I do meet a guy and it seems like he’s about to kiss me, should I tell him he’s the first one? I don’t want him to assume I have some experience and then be disappointed when I suck, but I also don’t want to make him nervous or put pressure on him to make sure it’s perfect or something.
