hmm, I simply think that logically, Yes men are designed physically for Fucking and incorporating the emotional and mental inadequacies tend to vie a lot into a Man's concept and reality of his sex life and personal identity, straight or gay.
Biologically speaking, while I'm certainly no scientist, the Penis and the Male body, is designed in such a way, that it facilitates innate pleasure derivative of the external stimuli upon contact to the primary sex organ, The Penis.
However; Because humans are complex things, Men, of course like Women, have the ability to attach feelings and ideologies of "it should be like this/like that" to a sexual encounter, with the only slight difference of the contrast in their physical design, whereas Women are built differently in this sense (its just anatomy gurl)
And so you get this dichotomization of:
"He can fuck whenever, wherever, whoever, because all he has to do is stick it in"
Whereas the Equally Male, however, receptive partner who idiomatically serves a different prescribed "Role", and so adopts a different "way" to the expression of his sexuality has this sort of conundrum;
"I have to take the Penis, do more work for it, accomodate a different lifestyle and be limited in my sexual expression mainly due to the physical limitations and pre-existing perfunctory mechanics of my body"
And because of the common misconception;
"If you like it/Dont worry about it/Are you doing it right?"
Leads many to believe there is a faulty link between the Physical ramification of bodily performance in Sex and the Emotional and Mental performance and in this case, Expectation, for Sex.
When in reality, simple designs, patterns and nuance of the Human Body, Sexuality and Enigmatic Idiosyncracies, clearly show the answers to the Questions "Why?" and "How".
