I agree that the man asses and tip fucking is a big problem with NRX. It's what keeps me from buying NRX scenes with "only beautiful" girls; the girls have to be exceptional in order to make the bad parts worth it basically.
I know Nick is very popular among gay men, based on the comments on his [spam], and that is fine, but shooting straight porn based on what gay men prefer to see seems to me a bit like going to gay bars to pick up women. Perhaps your scenes are underperforming because many straight customers find the focus on male ass a huge turnoff? At least I would prefer to see scenes highlighting your beautiful models, fuck balls deep in tried and true porn positions, rather than having the girls barely visible beneath a pile of man ass.
It is, of course, your studio and you do what you want, but the way you shoot scenes also affect sales, it's not only about pretty girls and letter combinations (DP, DPP, DAP, TP, TAP) in the scene title you know.
