Basically last week, girl making eye contact obviously asking for approach, I was a bit down but I just had to go for it, she receives me well, almost buys me a drink actually (I bought somehow, some misunderstanding), then we go back to the dancefloor where drum&bass is playing so obviously there wont be any sexy dancing so I ask her to go and sit and she literally does everything I tell her to, I did some light kino, she had no problem with me touching her. We start talking even tho music is super loud which I knew it was a bad idea but I just didn't know what else to do, she wasn't a drunk slut, was a smart girl, GF material even and on some things we hit it, on some not, I realised that the conversation ISNT going anywhere sexual which is my biggest problem and she just got bored, so did I actually! If I wasnt a horny dude I'd literally tell her yeah I'm out, yeah, we didn't click, I realise it, but I believe if I was anywhere near sexual she might have atleast see me as a hookup, 5 mins later I'm already super bored ready to leave, so is she but I'm like fuck it lets go for it, I tell her to kiss me, she says she can't she has a BF, obviously huge bullshit and I'm like right... here take my number call me when you're free, which ofcourse didn't happen.

Last night we went to even more mainstream club, some hot girl approached my buddy and he went for it but I realised she has one of those pushy best friends who will cockblock, so I went to wingman and meet them, turns out I started better than my buddy who was approached! Light to moderate kino, some negging, a little complimenting, I ask her to get drinks, she OFFERS TO PAY AGAIN, I'm like holy shit how do I do this, they all want to buy me drinks, we come back some light dancing, hands, moderate kino (means I went everywhere but squeezing her butt or breast) she doesn't mind and at one point she says uh I can't dance anymore and sits, I sit next to her and we talk for about 2 minutes, again nothing sexual and at one moment she stands up and is obviously bored, I ask her whats up dont you wanna hang, she says yeaahhh I have a boyfriend. I'm like what the fuck again...

There's a vague possibility that they really did have boyfriends and are just enjoying attention but honestly if that's true they're pushing it TOO FAR and basically cheating. I have 2 female friends that did that to me aswell, there was all sorts of stuff going but when she's supposed to cross the line ,they cut the cord.

I obviously need to show more sexuality verbally but I'm just confused how to steer a conversation from 'What do you study or Hows it going to I wanna do you on this table' without looking pushy, creepy or scaring her away.

TLDR:

Two weekends in a row girls that welcome my approach warm, dont mind kino, even buy me drinks suddenly get super bored even tho we arent talking for hours, literally 5 minutes, need help how to move faster into kissing / number / sex in clubs (not on dancefloor, at bar area or tables)

Anyone has similar experiences?
