Attracted to the wrong men

I'm a very attractive 23 year old guy, I'm tall dark and handsome. I don't sleep around much, and I'm not in a relationship either. I've been looking for a regular "buddy" for a while now but haven't had any luck. (I'm a bottom) I recently started working with my dad in the family business and the type of men that I see throughout the day are exactly what I get turned on by. Beefy, hairy, and muscular. Now, my dad recently hired a close friend of his he's known for 20+ years. And god damn he is sexy, exactly what I like in a man. Downfall is, he's straight. Not sure of his age, he's a little over 45 I'm guessing, divorced for 10+ years and has no contact with his now (adult) children. He gets no sexual action, and I know this for a fact. Is it wrong of me to want to ask him to have sex with me? Possibly start an ongoing discreet agreement? I mean I know he's straight, but he's not getting any action else where, he lives alone which is perfect, and I'd love him to use me. Any suggestions?
