Nearly everyone on PoF is there looking for sex. You can probably not fill out your profile, send a picture of your member erect in the attachment and the only thing you write in the email is a question about the certain woman's bra and panty size, and you'll get women interested women. The only game that works in this instance is to tease and flirt with them for about two weeks over the phone (don't go for a quickie immediately!), say you want to come over at late hour of the night and make you sure you are showered and dressed well. Tell her stories about crazy things you want to do for five minutes, call her over to sit with you on the couch and massage the back of her neck. DO NOT LET HER BAIT YOU INTO NOT SITTING BE SITTING THE WHOLE TIME! If she gets up and tries to get you to move for some stupid reason that isn't taking off clothes stripping naked just ask her to sit back down with you. Kiss her and begin to escalate with gentle massages and play with her hair. Just keep massaging her and get your hands down to her breast and crotch area. Eventually she may just start taking off her own clothes and yours.
That is how you get laid from off of the internet.
