I've recently started playing squash. The guy I play with is unexpectedly hot - also happily married and so far as I can tell totally straight. Thing is, we shower together after the match and I find him almost irrestistible - he's got a fine body and a nice curved cock, large, with a big ball sack. Hard not to get a boner when I'm under the water with him. I love showering with him, but I don't want to spoil our friendship or lose a squash buddy. Help!
