When you have some attraction, and you are getting a couple of IOIs, and want to build both comfort and start building sexual tension....

Start a game whereby you look at people, and try and imitate what you think their orgasm faces would be like. These can get a little out of hand, so you can always tease her by claiming she just pulled her own orgasm face.

That tends to lead to a playfight or similar. VERY fun if you are both tipsy and in a good mood. A good 90% + of the girls I have tried this with have reacted positively to it.

Always good if you find the conversation is getting boring after 20 minutes or so.

WARNING: DON'T USE THIS AS A GOD DAMN OPENER.

loves, snuggles and dirty cuddles
xxx

that sounds like a good thing to try!
its cheeky and has an underlying sexual vibe.
you could then follow it by a neg, and say something like "Oh my god no way!! is that your real orgasm face!...well thats a shame."

Yeah I find it really just suits my personality. Congruence = Acceptance.

For me, be who you are and not what you aint. If your actions are congruent with your being, you cant go far wrong. Fun game, though.
