Tell her you want to see her again before you go but it has to be this week because you have a friend coming and staying and it's been planned for ages that the two of you would be exclusive whilst she's staying.

Tell her you think she is a really cool, interesting girl and you would like to get to know her better but the timing really sucks but if it's okay with her you would love to look her up when you're back in town.

The best way to go into any sexual relationship with a girl is with the mutual understanding that the two of you are friends with benefits. i.e. Friendship comes before sex but only after you have already had sex? Do you know what I mean? You will have healthier longer lasting sexual relationships with these women if they feel like there is more to it than sex.

Once you have had sex with a girl once she is soo much more likely to have sex with you again unless you were terrible in bed or something, so if you are the kind of guy who likes having sex with multiple women then you want to have lots of girl friends who you have already had sex with but don't expect a monogamous relationship from you.

You can do the same thing with girls that you hook up with in your home town, they just need to understand that a relationship is impossible or very unlikely because of who you are and what you want out of life but that doesn't mean they wont still fool around with you, in fact for a lot of girls it is a relief to find a guy who isn't trying to rush things and know's how to play it cool.

Just out of curiousity where are you headed anyway?

Cool dude, I'm going to be in Europe for June/July, might see you around!
