Hey Keith, exhibitionist and voyeur here... I'd recommend Main St Video in Somerville when you're in Boston- great buddy booth and bj action... also the trails behind the Alewife T Station- where I like to go for a quick wanking session outdoors. The restrooms at the Longwood Galleria are also extremely cruisy. Good luck! Boston's a dried up place for the most part- your best bet for action is Provincetown. It's hard NOT to end up hooking up any time of the day there. Cheers!
