So I was at a party and flirting with girls.

Question 1: Is negging/banter/being condescending in a funny way a good to flirt? I'm a bit of an asshole so I find roasting/annoying people very funny and easy to do, of course the person I'm roasting laughs and also people around do but I'm just unsure?

Then I started initating kino.

Question 2: My way of kino is doing things such as tapping their faces like a baby, slapping their arms/legs/ass, choking them (This is after I've got to know them a bit and I've done basic kino). Are these bad things to do? After tapping their faces I've had a few people tell me that I shouldn't hit women, I've had random women walk up (women I wasn't even hitting on) slap me and I've also had a few random men try to fight me. It's strange because the people that I'm doing it to normally find it fun/different and usually laugh and play fight back, I've never had a girl say "What are you doing?" or "Stop doing that".

After the party had died down a few of us stayed and slept upstairs, I was in my own bed and this girl I was speaking to earlier in the night got in next to me whilst her friend, and everyone else, laid down on the floor, did she come next to me because she liked me or because she just wanted to sleep in a bed? (Next to some random guy she just met that night, she also started randomly started proclaiming she had back pains when she climbed next to me). Anyway after a while I shifted into position to spoon, she said nothing, I then put my hand on her stomach and again she said nothing but when I lightly started stroking her stomach and putting my hand into her waistband she said "no more of that" and grabbed my hand out of there so I stopped, a while later I re-initiated and was touching her pantyline but it felt awkward, almost like I was forcing it because she just laid there in an awkward position saying nothing. Is this the right way to start escalating in this position or should I have done something else?

The next morning we woke up but it wasn't at all awkward and I have another party with her soon, what should I do?
