okay, so this guy asked me out so we're going to the movies next week, but we had a relationship late last year [we didnt go out, it was more an unofficial thing, but then i broke it off]
i know he loves me, even though we're only sixteen, and hes turned down other girls for me, and he would do anything for me. hes incredibly cute and sweet and just amazing, but im scared that im gonna make the same mistake as last time and let him go. i trust him with my life and all my secrets, and we feel each other up in biology under the desk (corny i know) and i know im kinda skipping from describing him to this, but few questions :p
1. how do i get my hand in his pants in bio when hes wearing a belt and the teacher walks around..?
2. i normally shave my vag [im an ex-gymnast so since i hit puberty ive always just shaven down there cos i was always wearing leotards and was worried it might stick out] so should i keep shaving, or let it go natural?
3. he has a really big dick, 7.5", and we're both virgins, so im really worried it'll hurt when we have sex, so is there anyway i can like prepare myself for that?
4. good techniques on giving head/handies?

thanks in advance, and please dont judge me and tell me im doing something wrong :)

You're 16, 7.5" isn't big, and you're both being stupid and letting emotions cloud judgement.
