For massages (with or without happy ending) I can quite easily go to the same girl over and over again, simply because it's hard to find someone who is right for you.
The problem for me is that if I sleep with a girl too much (including my SO
) one of three things tend to happen:
1: I start to get bored of them
2: I start to like them too much
3: I start to become their friend
...and I mean real friend - the kind of friend where extra privileges feel weird.
Now, if I don't see a girl regularly then I can easily see her 10+ times over 2 or 3 years.
But, if I see her more than once every one or two months then there's a good chance that it will become option 1, 2 or 3
