so basically I am a virgin and have a 4" inch dick thats fairly thin as well , and my question is is it even possible for me to penetrate a girl ? what are some good positions to use
Yep, you'll be able to work it just fine. Doggy style probably gives you the best and deepest access.
I disagree. Doggy Style has the buttocks preventing you from making deeper thrusts. Missionary is far more suitable as it has Pubis contacting with Pubis - as close as you can get.
your good to go, alot of times my wife rides the first three inches with my cock flat against my stomach her on top sliding back and forth and she cums all over me. Dont put huge expectation since its your first time just have fun the worst thing you can do is worry!
Id say missionary with the girls feet up on your shoulders.... opens her right up and youll get in deeper then any other position..... or sit in a chair and have her sit in your lap facing you..... this is my favorite position and it gets you nice and deep.
i would go with what grain said out of all the positions mentioned. that and work your tongue muscles out.
missionary and the further she spreads her legs the better, just be sure play with the clit and all will be good.
This could either be a legit question (based on physical maturing yet to happen, meaning, you could grow), or it could be mean...and I'm assuming the former. So, if you are still in your teens, you might not be at the final stage of growth. Avoid size queens. Avoid people who like humiliating guys with smaller cocks. Best positions will depend on how mich other body is in the way. Small butts? From behind is dandy. If, however, you have a belly, you will be fighting that. So, get rid of excess flab, which will reveal some more penis, actually. Scissor positions work. And Skip is right, get your tongue in shape. Don't be hesitant, don't be lazy. Flap like a hummingbird.
I've been with a smaller man a few times. 4inches sounds about right. We did missionary position and cowgirl. I was able to get off in both positions. I don't remember anything being different due to his size. He was a big hunk of a guy too and it was ironic that his penis was so small.
