do i say i'm a virgin?

Ok i'll try and keep it short...

me and this guy (have known and flirted with each other for like a year)started dirty texting/picture messaging each other recently. we're gonna meet on friday. Not sure if we actually will have sex or just fool around and stuff. we're not in a relationship or whatever just having fun pretty much (and i'm actually cool with that)

I'm 17. have pretty much felt ready to loose it since i was about 14 just has never actually happened for various resons (e.g with the last guy people walked in or other e.gs... when we've met been on my period or the appropriate time at a friends never came up etc). I've done other stuff with guys like foreplay things and like "dry humping" - same movement, right? pretty sure my hymen is broken already so no danger or bleeding and stuff.

do i tell him before friday? if so how soon? or should i just go for it? cos if i tell him it might make him think i wanna get all serious when i don't but i don't want him to expect me to be good and get disappointed?

Oh and ages ago we were talkin about losing virginity and i think about twice in the last year i've ended up saying that i'd never had sex (these 2 occasions were about 3 months apart) and both times he pretty much said "ohh! what?? i thought you had haha. oh well that's fair enough i wish i'd lost mine later"

yeh i know its a little bit sl*aggy....
