As weird as this will sound, I have yet to try any of this because it seems very uncomfortable and perhaps dangerous even, if your not sure what your doing and just stuffing it around. lol
(That wasn't the weird part by the way)
Uh, the part that sounds odd is that this technique seems like it would fail the moment you get "horny".
I mean, come on! We are at an Anime convention and there are pretty girls there. (Real girls)
I don't want to come off as some perverted creeper or something, but it IS a legitimate concern.
