Hello and welcome to ehealth...Young Worried and Weird:
First of all you may be young but give yourself some time to grow....Worried:..This is just part of growing up....Weird:..Not really...Just confused with life....
I would say that you get numb hands and dizzy feeling because this is not a comfortable position that you are putting yourself in....Sex is a beautiful act of love but when it is used as an amusement as something that everyone else is doing and shows that you are grown up, it can be confusing and scary...Hence the dizzy feeling and numb hands....
I would say that you pull back from orgasm and turn your attention to him because you are self conscious...Your body is a wonderful place and you just may not be ready to share it with anyone yet.....But this is not bad....It will come with time...
I would say that you bleed because you are not juicy enough and stimulated to the point where penetration is easy and feels wonderful...Instead it hurts and you are sore because it was forced instead of welcomed...
Honey, you will orgasm when your body and soul welcomes this pleasure...Don't worry about letting him down.....Take care of number one first......That is you...
These are just my thoughts...I send my good wishes to you
Caroline
