>>87904622A vagina isnt like a place where there's only one pleasure button. Sure going in and out works but that's just one of the faucets.
Try touching your bicep. Press it and you feel it right? not try pressing and massaging, pressing and going up and down, etc. If that were an erogenous zone think of how you would masturbate it, since a penir can be jorked and everything is more or less just a plus. Vayjayjays have more options due to the walls AND the entrance being sensitive
