[Solved] P-spot topical gels? Do they exist?

I would have to say no. Unlike the g spot that is directly located with in the vaginal canal, the prostate is seperated by the rectal canal so anything used would only affect that tissue and never be absorbed or applied to the prostate unless it was delivered directly via the urethra or a long needle injection. I would not recommend either as the needle sounds painful and the other could give you a uti, infection or worse if not used in a sterile environment. 

I'd asked once before if there was something that could be taken internally, and I forget what the answer was. I think it was something along the lines of "Not really". Oh well, just a thought.
