I can understand the OP a lil bit. Back in the day, a woman would almost have to pull my dick out and start sucking it for me to get the hint
[her pulling my dick out and slurping away, after many wasted signals] me: Oh, so you want to mess around, huh? I get it now. Why didn't you say so?
Seriously, dude. Cop a feel or something (a slight, gentlemanly feel, not a horny nerd teenage grope). Or when you were 'getting dirt off her back', a hand on her waist while you stand extra close to her (close enough that your dick would press slightly against her ass).
Yes, it seems that she pretty much wants to be taken. She wants you to make the move.
Don't be like me, dude, looking back at the [seemingly] 100's of wasted opportunities, thinking, 'damn, I could've hit it'.
It will haunt you forever...until you become a seasoned hobbyist and get laid enough to forgive your young, dumb ass former self.
