okey here is my story

Last night i went to a party with 2 friends and 2 girls that my friends knew.
When i saw the girls i imediatly introduced my self to the girls. Girl A asked me about my name 2 times
she told me that she needs to hear it 2 times to remember it(maybe ioi).After that i had a small conversation with the girl B in the back(we was in the car till we arrived to the party,i was sitting back also)
Now at the party i had small conversation with both girls i said some jokes we had some fun then i started to escalate(not very sexy and not very agresive) both of them(not in same time). i had a good eye contact with girl A. At that party also i knew lots of guys so, many came to me to say to hi and have a small chat(DHV).
After some dance we went to sit in a quiet place all together.Then i sat next to girl A. I had sat so close that our bodies where in touch all the time she was okey with that i guess but after that i didnt knew what to do .I was thinking to isolate her but didnt knew how to do it

So guys what you think i should have done?Do i did everything wrong?Should i add her in fb and hopefully arange a meet with her ?

Put your arm around her when you are sitting next to her. Look at her in the eyes for a second, wait a moment, look at her like you want her, hold and kiss. No words, just body language.

You can even give her a quick kiss on the cheek when you put your arm around her and see how she reacts. Maybe give her a big hug.

Another way, grab her nearest hand with your furthest, lean back but angle your body towards hers, give her hand a kiss and look her in the eyes with the "I want you" look. If she's ok with it use your other hand to stroke her hair a bit, then lean in slowly and go for it.

Just fucking escalate for fucks sake. Ugh, so many guys are scared of being shut down, it doesn't fucking matter. Escalate from first contact with them. If you don't ask the question (ask with you body not your words like a douche) you won't get an answer!!
