To be perfectly honest, I don’t think the product was created for use with the male version of Genesis. The promos leave a lot to be desired. In fact the first promo is practically a joke. Look where the female’s head is. It’s blocking any view of the differences between the male and female versions on the chest. Which is where it counts.
If you look at the add on texture pack, there isn’t a single promo of the product used on a male. Maybe this is one of those products where the vendor should have stated it was for the Genesis female so buyers could beware.
The bodysuit is tight which makes putting another product under it difficult. Putting something over may or may not work.
If you know how to make second skin textures, you could make one. It’s been awhile but couldn’t you make a torso texture and apply it using the LIE?
