just go up to a random girl who isnt getting alot of attention at a party, sit down next to her start talking then stair into her eyes and just go in for a kiss...eithr she pushes u away or she doesnt. if she pushes u away then just be like, fuck u bitch, then go try it on the nex tgirl...eventually one will be horny.
then step 2:
about 30 minutes into kissing, just pull ur dick out and kind of slowly move her hand to it, then if she starts working be like "do u wanna go someplace more private" get a bedroom and fuck her brains out, then if u want a girlfriend get her number in the morning
