The Male G-spot - Fact or Myth

[tlover]

Enlightenment needed on this subject.
I have had some great orgasm's while my girlfriend has put a finger in my arse while making love, unfortunately she isn't keen on doing this too often.
This makes me uneasy asking her to do it and exploring it more.
Anyway ive heard that the prostrate gland is like a male g-spot and its located somewhere up the back and when stimulated it produces wild orgasm's.
Maybe she has hit this spot, mabey not and i just like the feel of a finger in my anus.
As shemale lovers i think most of us like the feeling or at least he idea of something up our arses and i would have thought someone would have mentioned the g-spot subject at least, but no it' all a mystery.
So can anyone out there enlighten me please, exactly where is it, how is it stimulated, and dose it work or is it just a myth.
