I'm guessing girls might be more useful than boys with this due to more experience of said problem but basically last night I was out someone and a female friend of mine (who was pretty drunk whilst I was relatively sober) kept invading my personal space in a really annoying way. She didn't do anything by any means indecent but just kept kind of putting her hands on me and clinging to me in a way which'd be entirely fine if you were in a relationship, or even really close friends with someone and both comfortable with it, but felt pretty invasive nonetheless.

In the event I said nothing 'cos, as I say, she didn't cross the line into overtly sexual behaviour and I couldn't think of anything to say that didn't sound like an overreaction but was pretty pissed off about it and want to have a sound plan next time.

Maybe I am over-reacting but

a) it's my damn body and I only want someone to touch it if I'm comfortable with 'em doing so.

b) 'cos I'm single it's not really in my interests for a girl to act as though we're going out.

c) basically a) re-emphasised.

So, any advice?
