The romans were alpha as fvck and they used to fvck men without losing any musicality in the eyes of society. You telling me snoop drake and his ilk are harder than the romans?
The act of "penetrating" a man does not make one masculine. I define true masculinity the ability of a man NOT to even slightly entertain penetrating a man or being penetrated. A true Alpha masculine str8 man is neither afraid of gays, nor slightly tempted or interested.
Once a man desires another man, his masculinity is compromised.
