At what point would be a dutiful time to squeeze my GF boobs?

we have be going out for almost 5 months now. when we get out, her boobs are like staring at me. i lately wanna go and give'em a nice SqUEZe! but surrounded by the back of my mind i know she for a while uncomfortable. i dont know how much longer to linger...Can someone please tell me what to do here? she is one nice girl. she probably would've done sumthin to show u that she requests u to.
but since she hasn't, DON'T & NEVER assume that she does. or any other girl. u might end up doin sumthin that'll cause u guys break up.
U'LL KNO ITS A GOOD TIME TO DO SO WHEN SHE tells u so. never assume.
lol merely go for it
