Interesting post about the internet. I hadn't really thought about that.
But that's not why I'm posting this . I just wanted to add my voice to the advice you've been given here - try to relax a bit. And, at 19, I would definitely avoid the Viagra. Accept that it's normal to be nervous especially at first, and it's not normal to perform like a porn star. Some of the best fucks I've ever had (and I'm approaching 70 yrs old) started out pretty relaxed and lazy and then the thrusting gradually got deeper, stronger and more vigorous and then developed into that mad sweaty frenzy of being fucked senseless. Even at my age I haven't quite said goodbye to the "mad, sweaty frenzy" but I have to admit it is less frequent than it used to be. However, slow and lazy is still as enjoyable as it ever was so just relax into it and see where it brings you. Remember too that a lot of women prefer a slower gentle approach and don't like to feel rushed. A professional working girl, unfortunately, has to pay some attention to the clock so if you do continue to visit escorts check out the reviews and look for a girl who might be less of a clock watcher. Enjoy your sexual exploits and remember, sex isn't dirty - but it is when you're doing it right!
