Wanting a one night stand, not sure how to go about it.

This is something I've been debating doing for awhile now. I've been struggling with my sexuality for some time, and I think this may help me make a move toward understanding what it is I want.My initial thought was to go to m4m on Craigslist and find someone interested in meeting up for the night (just wanting to give head, maybe receive). However, the site feels sketchy and I'm nervous about STDs.Does anyone have experience with this? I'm nervous about the whole endeavor, of course, but mostly excited. What are signs I should look out for, to avoid a bad situation? And outside of CL, or Grindr, what options do I have to find someone?
