Machomansgris: I prefer men. Women seldom turn me on. I like men whose secondary sexual characteristics are very pronounced. (that is all the physical charactersitics that develop from adolescence onwards and distinguish males from females.) I am always surprised that the very features that mark the differences between males and females, between children and adults, are not valued more highly, and valued more the more noticable they are. It is secondary sexual characterstics that make a man a man. So why anyone would like twinks is beyond me, I'd rather have sex with a woman.
Well, here they are (at least the ones that make my head dizzy, and that's most of them)
Swarthy body, facial hair, male pattern baldness, low voice, muscle mass, broad shoulders narrow hips, big hands and feet, large package, bushy eyebrows, square jaw.
Incidentaly I like fat men but they have to be fat in the male way, i.e. abdominal fat, big bellied and square necked. Fat creases at the back of the neck are a real turn on.
At close range, body odour. I have a complete arm pit fixation. The smell of fresh (one day maximum) arm pits makes my head spin (better than amyl nitrate).
Total and instant turn offs are men with female attributes: no body hair, no musclemass, wide hips, sloping shoulders, X-legged, soft subcutaneous fat especially round the hips or thighs, high pitched voice, feminin intonation, effeminate body langauge, pretty face, Eau de cologne - Yuck :-/
