Here's something i do sometimes:
Let's say I'm really busting on this girl hard and i'm getting to the edge where i can ALMOST sense she's starting to get insecure,maybe if i go much further i might actually hurt her feelings....I'll occasionally make a joke about myself. So if I'm really messing with her and making fun and teasing about her or her personality...let's say The last thing i did was call her a weirdo. i might say....."But you know, I'm not all there either. i guess it takes one to know one".
So it might be like for every 6 jokes at her expense, i might joke about myself once. (That's to give you an idea...I'm not keeping count)
The whole point is to just have fun with it. I love to make women smile and laugh and have fun while i'm doing it.
