I agree, given the amount of women who expect frequent attention, it's getting a bit detrimental to gameplay.
Vampiric Awe certainly helps but not enough. Doesn't work on some girls like the giantess and even though it restores love points, girls are "not in the mood" too often as well. Those pastries are not unlimited. Not everyone wants to be a vampire, either.
My advice would be to add an extra grace day to each girls timer before they even start losing affection or care at all about lack of visits, for starters. Perhaps reduce slightly the amount of women who care about that at all, as well. The giantess is particularly annoying, maybe make Awe work on her at least.
Oh and while we're at it, perhaps add a timer to the imp when you refuse to have sex with her. She keeps asking again every other screen, it's a bit much.
