Man, two meters tall, weighing 100kg last time I checked. Currently between 20-25%, I reckon.
Thanks to great genes it's really hard for me to get fat(spent the last three years seriously doing nothing but sitting on my ass, eating unhealthy and too much, drinking at least 1,5l Pepsi every day) and I build muscles quickly. There's a huge lack in willpower however, so even if I put my mind into it I grow bored fast.
I'm fairly indifferent as to how I look, though I gotta admit looking at old photos of the really slim me makes me a bit sad. I feel that I look a lot more manly now however, so I'd probably want to go back to <15%, but with more muscles.
Don't think society thinks anything about my body shape. They're probably more concerned with my waist-long hair.
With men in general I feel the expected body type these days are the 15% photo. Hairless, slim/fit men.
As for my ideal girl; I've been with most types, except the ones over 35% which I find disgusting, and my best experience was with the really fit ones. Can't identify the type on the pictures, but I suppose it's around 15%. I prefer the 25% build however.
