Yup, all of the above. I met my guy online, also. Did it off and on for a couple of years. I really met some doozies but no one that ever made me nervous or scared in any way. I "do" think that I probably went out with a couple of M'd men, but they didn't interest me enough to want to date them twice so never found out for sure. Just a gut feeling on the first date.
Just be careful/safe. There are good men out there that are looking for the same things we are.
