bjorn borg will forever be my all-time tennis hero. and he was early masturbation fodder--i thought he was so damn hot. i remember getting so worked up watching wimbeldon with the family i had to take multiple jack-off breaks.
lendl most certainly hung.
how about
boris becker? his tree trunk solid body looks like it would have a matching cock (gotta love those tennis player legs).
as long as i'm on the topic,
marat safin is a stud.
