Thing is though Harry, she'd probably take sex as a "next step of the relationship" thing. I could perhaps tell her beforehand that I don't want a relationship, but that requires balls which it appears I lack!
I don't have to lose it before the holiday, it'd just be nice. If I don't, losing my virginity while there will be a big priority, and if I fail, it'll put a downer on the holiday. By getting my end away before I go, it eliminates that possiblility!
I know I shouldn't mess her about, but telling her exactly how I feel could go down a bit badly, and as I have to work with her indefinitely, this isn't ideal.
Thanks everyone so far.
