Glad to be of help. I was reluctant to write some of the points below, but after much consideration, I have decided to write them down anyway, as they might be helpful to other readers:
Much of mainstream propaganda about how guys and gals should behave in an romantic/intimate relationship is simply wrong . . . and deliberately designed to breakdown relationships and families, so that employers and tax/redistribution monopolies can benefit from the carcass.
We go out and have fun and sometimes she's not up for sex. So it's about as close to a vanilla relationship as you can get.
Something is wrong if "sometimes" is anything more than extremely rarely, and unless she makes up for it the next time. None of my vanilla relationships ever involved the girl refusing after sex having already taken place on previous dates. A vanilla girl might turn down initial advances before I ever had sex with her, but not after having already had sex on previous dates, not even during the nearly a decade long marriage that I had. In fact, my ex-wife and I had some of the best sex in the few days after our divorce petition was granted by the court, all initiated by her. Having never given me the "dead bedroom" treatment is likely the primary reason why my ex-wife is receiving from me multiple times more than the divorce decree mandated.
In the 400 or so dates I have had with my SB of 3.5yrs since sex started on 3rd date, only two times did sex not take place, both due to her being in pain from having small surgeries (and I took her to/from the surgeries), e.g. a nose job that she yearned for ever since when she was a teenager a decade earlier. Luckily the 5-figure nose-job didn't change much of anything, because I liked her nose just fine.
The girl not wanting to have sex nilly-willy is not normal even in a vanilla relationship, and should not be rewarded, unless you too want to get out of the relationship (and waiting for her to get you mad enough to quit on her). Sex is what she brings to the table (whether in sugar or in vanilla), the equivalent of her random refusal would be if you refuse to pay allowance nilly-willy, or a husband deciding to quit his job and stay home to play computer games.
3.While I do not subscribe to B.F.Skinner's theory that every human being is an Operant-Conditioned robot, there is a high degree of relevance to his theory due to the biochemical basis of the human brain: a very sophisticated robot whose electrical circuits are implemented in water (electrolyte solutions) and carbon-based compounds, instead of silicon with lithographic etching. Subjective love and attachment may overcome obstacles in the short-run (due to Extinction Burst to some degree), but sustained / repeated negative feedbacks for your effort will make you ditch her. So inducing her to behave in a way that makes you happy and satisfied is actually in her interest and to her benefit in the long run. That's where "being the parent" responsibility comes in.
Statistically speaking, girls are more likely to be selfish towards the lover (her selflessness is reserved for her children), due to biological reasons: if men were just as selfish and refused to make a stand to protect women and children, lions and leopards would have taken all the slower-running women and children before humanity ever got a chance to walk out of Africa. However, it's just no fun staying in a relationship with a woman who is too self-centered, not invested in the relationship, or treat her lover more harshly than she would strangers. The primary advantage of sugar-dating is having a wider pool of young women to choose from, so one doesn't have to be stuck with someone who is "spoiled."
Most girls in the bowl are too young to realize that their few years of attractiveness is little more than their gene's way of helping them securing a productive man for her reproductive project. Her "blossoming professional career" is a plus if it keeps her time occupied (so that she doesn't devote all her time to showing off on social media) and makes her content, a minus if her job gets in the way of relationship with you. For most men who can actually afford to sugar, what a 20-something yo girl makes from her job (especially after tax) is a relative pittance.
