Naw, both are for girls too. I like both a good squeeze and a nibble/tonguetwist. And as for the TF...it's a less hand-cramping way to go about it, imo...plus I kinda find it hysterical...I find penises hysterical but I'm good at my resolve I won't laugh in your face, lol.
This is absolutely true though. With the boob squeeze I specifically like it with the pressure on the outside going inward...how the hell would any guy know that unless I showed/told them XD
