hmm. when I was much younger I'd have killed to get some info you requested. since you did ask..... here.
ahem oh boy
first off, if done right, the orgasm is nice but it'll be the dullest part of the whole process.
thoroughly feel all locations with your hands, learn where to assert preassure. this
important imo. put a good bit of preassure on it and you'll feel just how big you really are, the inside will feel . uh interesting.
learn how to lubricate. most dudes and dudettes have fifty billion different things for this. nothing is as good as natural secretion, though, or spit. rub the tip lightly, maybe rub the outter head with the bottom of your thumb. then spread the film.
remember, too, that after you do these thingsy ou'll be sore off and on but its worth it. before long you'll be able to do a lot more with it , for a longer tiime, and much more enjoyment. cup it, flick it, rub it, use a soft cloth occasionally to toy with it.
start unzipping your pants a little when you know you'll be alone. just enough where if you get hard it'll be close to coming out. try to ignore it :> then just keep at it.
eventually, if you have the energy, you can go for a long time. i went for about five hours one night. i couldn't move the next day though
take your time. if you just get off quickly, you're missing out on a lot of fun.
its not just a jerk. its an art.
