Hey dude, totally agree with others!!
Try it allllllll!!!! There isn't enough time in the world for everything... so get a head start and try to do it all :wink: ... I'm 28, and everytime I'm with my lovely lady, I find something new I love about her, and there's always something new to do :smile:
That being said, if you can find a bed that is waist height for butterfly... it's much easier if you're standing, and you can get some really good hard deep strokes going... if you get her really really turned on, she'll love it hard and deep :wink:
Sometimes, it's more difficult to cum in one position rather than another, but i've never found it impossible to cum in any position, and there's nothing stopping you chopping and changing... my gf and I regularly go through 4 or 5 positions at least before one of us cums!!
Also, toys are a good thing :wink: heh heh ... yes, I'm a dirty bastard, what can I say? I love to play!!!
That website is great too though, loads of things for you to try :smile:
My personal faves I have to admit though, are doggy, and then a close second: absolutely every other position on the face of the planet that we are capable of getting into!!!!!
Anyway, hopefully you'll get to practice soon :wink: heh heh
[edit in] Ooooh, I know one that isn't on that site that is good... just finished perusing the site... anyway: find a dining room style chair (straight back, no arms) and you sit on it, she straddles you, and moves in a "belly dancer" esque movement while you're in her... it will rock your socks :wink: and she can hold the back of the chair to help balance... ideally, resting her feet on the floor, but I guess that depends how tall you both are, or how low the chair is :smile: have fun!!
