There is a very serous lack of clothing and their textures for male characters, but a special lack I see is in touch with pants, loincloths, jeans or trousers or even more evident on catsuits. When a merchan does one (probably because they are used to create pieces just for women), this clothing appears "plain", unusable, unreal, because they lack the male shape this naturally forms...I am talking about the genital conforming, the bulge that explains this is a male and, we like it or don't, under this there is "something that must be" that causes wrinkles and bulges.
Please, create male fantasy or casual clothing with a suitable morph for genitals.

I totally agree... The morphs for the zipper area on the male model pants make him look like a mannequin... I also would like to see male clothing that can form a pile on the floor or in laundry hampers.   Or clothing that you can hang on hangars or hooks... (you hang your pants and shirt on a hook in the locker in the locker room or hang it off the top side of the locker door.  You throw your dirty cloth into a pile in the corner of the bedroom or closet.)

That's I call a morphologically right pant. This is one of the few true serious male clothing I have seen, it's "Dagon" for Daz's Hiro, and it can be seen and noticed there is "something" under the zipper, as this must be that way if we are rendering a male person and not a mannequin as you said. This doesn't look like a cardboard plain "unisex" clothing, but like a true pant with a male character in mind when modeled.
