Kevin Slater, nice, smart, professional, really big, and a good escort. Has reviews on Daddy. Otherwise, his website http://www.laterslater.com/home.html
Obviously if Rocco Steele is escorting he would be someone who is huge. Doubt that he is under 35. You also might read this thread and see meet your requirements. http://www.companyofmen.org/threads/huge-cock-recommendations-in-los-angeles.106090/
Oooops. The original post is about a Zach Scott, an escort in NYC and not the current porn star/escort in Las Vegas or about a theater/screen/TV star in the 40s-60s. I really do need to pay more attention. P.S. Screen/Stage/TV star Mr. Scott died in the 60s at the age of 51.
Well, if you do end up meeting with Boston Miles I hope it ends up well. His pics/videos certainly seem to show he can play a jock-sub role. Nice cock, nice ass.
