Cruising for sex

I spent most of my day yesterday touring several local cruising parks and found the experience pretty terrorizing. I never got close to being hit on, but just the sneaking around and getting way off the beaten path where I thought I might find other guys really stressed me out. I don’t think I could have come close to getting it up if I HAD been hit on! Now I feel like I have created just another connection in my brain between wanting sex and serious stress. I feel similarly when I visit the baths-no chance of getting an erection there. So, I guess I know what to avoid, but I am just crazy worried that my hookup days are over with no prospect of a regular. I could barely even take care of myself last night.
Thoughts on the unique pressures a top feels?
