I couldn't resist speaking to this topic....
1) The websites are the new bar and flakes, twinks, bears, daddies, idiots, drunks, druggies, assholes, average joe, leathermen, rednecks, big black cocks, truckers, etc… are on it. Some are nice eye candy others are downright fugly. That being known and out of the way one MUST acknowledge that the anonymity that comes with the internet sites support and encourage dishonesty, in other words lies. A stat that is kicked around is that nearly 70% of all, ALL, people on the Internet lie when it comes to describing themselves compared to 50% who do so in person. That is a powerful stat to keep it in mind during the next hot IM.
2) Timing is everything. The sites are there for a conversation starter not necessarily an automatic lead in for sex just as the bars are meeting place for conversation, a drink, and maybe sex. A bathhouse is about the only place I can say would be solely for sex (I think most know the routine there too). There could be factors that cause me not to play. I've had hits from sites when I'm not in the mood, I don’t have time, or from people I don't care to fuck around with (see #1). On a personal note, I admit that I'm cynical and suspicious of any contact, an occupational hazard for me. My stance has saved me from a number of bullshit sessions initiated online or in the flesh.
3) Distance maybe a factor. Why should I schlep 30 miles or 30 minutes for an hour, at best, fuck? Driving an hour is not an economical use of my time or gas despite my degree of horniness. This is especially true when, and if, I discover that you lied about appearance, stamina, ability, or sex play (see #1). Being closer increases the likelihood of at least a face-to-face meeting, which could get you into my sling. So I admit if a trick is more than 5 miles from me (and I live in a metropolitan area) a trick’s chances of reaching my sling isn't great. On the other hand, five blocks will get my attention and at least a beer.
Lastly, it is all fun, Don't take it so seriously. After all, it is entertainment and sometimes pleasure.
