Should I tell him?

Alright so I've never been the kind of girl to be like "yeah, that's my boyfriend"

If we're a thing, we're a thing and I'm loyal

So me and this guy are a thing and he's 21 and I'll be 19 on the 26th of April (I am a virgin, he is not and we are both aware of this and have talked about it)

So basically he has told me that he wants to be my first time and he's willing to wait as long as I want

However, the last guy I was with I was head-over-heels in love with and he ended up dropping me because he found out I was a virgin 3 months into dating

I have not told this new guy anything about the last guy

All he knows is that I was hurt, but he doesn't know why or how

And honestly, I'm both scared and couldn't care less to have sex with this guy

Couldn't care less as in I would have sex with him whenever I'm ready and scared as in I don't want to be hurt again

What should I do?

Should I tell him about the last guy? Or would it be irrelevant?

Honestly I just don't want to be hurt again because it will ruin me and I'll probably never be up for sex if something happens
