Can someone please give me some advice i'm a bit anxious.....

I think that might be the problem actually you are too anxious. Relax some and try not to think about it and it will happen. Many women go without having an orgasim for years and years. This happens to men too. Usually for men it is anxiety about things either in their life or sexually related.

its harder for people that have just started to learn about sex/masterbation.

When you're younger it could take much longer but as you get older and learn more about your body, you will understand yourself better and learn little tricks to get yourself to orgasm.

from experience my first few times i worked up a sweat and my right AND left arm were sore and nearly cramping and my "you know what" was all chaffed before i could reach orgasm

i wouldn't worry about it and have fun kid

I guess if you are 16 you probably are not on any medications that could cause this, but I do know some medications can cause this.

you know you might actually be blessed and be the best woman pleaser in the world.....

if you cant come you will go on for hours and every woman will want to sleep with you....

When I was young it was just the opposite always had to think of baseball or something, come on don't laugh, you know the story....

I'm now 45, fresh air makes me hard as a rock that's never been been a problem, no viagra for me. However I also now know my limitations I just typically don't initiate more then every other day. It's really not just a blessing, yes we can go for long periods hour and I have had multiple partners in a day trying again because she's sore or wore out, but I have to keep trying this is extremely frustrating. I admit you can make them very happy but this is no blessing...
