I'm probably in the minority (at least of those who'll speak out), but this kind of stuff can be very intimidating. Energetic and strong are great, ******* me...sorry, not so much.
Fortunately, I've had some good experiences with guys who've wanted only my pleasure, and who wouldn't hurt me for the world. If I hadn't, some of the stuff on this site would totally scare me off. For a newbie, it can be very intimidating. If that's not what you're looking for, you wonder if the guys will figure you want it that way anyway, just because you're on the site. And because of that, you may not even try.
Just a few comments.
