From my experience in writing descriptive narration, when you write, apply the the idea that you can make them... see, smell, taste, touch or hear. For the description of a man. Many women like the idea of well muscled, but not swollen. The idea of Mr Olympia isn't what allot of women like, they prefer the more sculpted v shape, with bulges, but not to the point that the guy cant touch his own shoulders.

So if I were to describe a man...

-----
He walks into the room, the light behind him highlighting his chiseled features. Strong arms and large hands on narrow hips. As he approaches her, each muscle in well toned thighs ripple with flexing of each step. Stopping he towers over her, and reaches down and effortlessly scoops her up into his large protective arms. She is cradled against his sculpted chest. and her hip is against his member causing them both to feel a stirring below. She could smell his strong musk sent. Arrousing her desires for him even further.
----

As the scene progressed you could become more descriptive, if she were to touch his head, talk about how the hair flows through her fingers, if she handles his dick, talk about how it feels in her hands, if she gives him a blow job, talk about how it feels in her mouth.

Remember the senses we use to experience our surroundings, and write for the senses. The mind of the reader will better experience each scene if you do.
