identical twin, identical penis?
this question has been bugging me for quite some time now; do identical twins have exactly the same length, girth, shape etc. penises. This would then prove that penis size is genetic and not related to external factors, and that however hard we try we cannot influence the size of our penis.
Because sometimes one twin is taller than the other or has a slightly different facial structure.
Anyone out there a twin or had experiences with twins.
Another tidbit of information apparently if one twin is gay the other has a 60% chance of also being gay
