Well the male G-Spot is his prostate. Yo can reach it best thrue the ass and i belive moste if not all men would really enjoy a good Prostate massage but there is this strange rumore that it makes you gay takeing it up the ass. it is only a sex practice. just like Masturbation or missionary. Gay means that you would fall in love with other People of the same sex witch is total ok as well.
I always thought it was strange and "only gay guys like anal contact" But, after being in a long term MFM relationship many of those old beliefs fade and lines begin to cross. Anal stimulation is a huge turn on for me and I am not afraid to admit it.
