I'll be the first Colin
First off, men vs. women....vive la diffrence! It bothers me that the women's libbers try to make women 'equal' to men in all ways....the fact is, we are very different.
I was 14 the first time, with my b/f of the same age....I was thrilled to do it! haha
While I agree for the most part with Forest, I DO NOT agree that for women/girls it is 'emotional'....not the first time! (at least it wasn't for me)
It is many things.....but curiosity and hormones top the list. (just like the guys)....also, attaining a sense of 'adulthood' plays a part.
