What On earth Does this mean?

Well heres what happened, I was surfing the net, when some guy came onto a chat i was on and gave me a link to "cool stuff". It was porn, annoyingly, but not massively hardcore porn, it was just a picture of a naked woman.

Now ive never seen such stuff before in my life, and I was not sexualy attracted by this at all ( I am a man) Suprisingly, The first thing that happened was that I thought "I wish I had a body like that", All the "porn" done was make me feel bad about my own (male) Body, when compared to a female body, the whole thing has just confused me. Ive Never ever had an orgasm before and I have, Up Until now, considored myself Asexual, but now Im not sure what i am.
