Agreed with most things you said (apart of NTR, that is not my taste), my only problem is that main hero carry his virginity like some holy grail, i cringed hard for him as he furiously defended his virginity from that [spoiler] who were ready to r*pe him (her arrogant nature shouldn't listen to his pleas), if i was on his place, i would agree x10.
for me the fact that he treat his vitginity like some allspark cube is what makes it good, theres so few games out there who really care about male virginity, and if some game care, there are more fewer game where we as a player can save it, and the fact that this game where its world were written around sex (i mean spoiler, the main lore is about sex goddess afterall) make it more awesome
