Masturbation, that's what Bilbo Baggins hates!
This reminds me of beasly (anthropomorphic animal) depictions of "the devil". Denial that humans are also animals, that supposedly we're only animalistic if under the control of Satan and demons, etc. It's like if the ideology is gradual "spiritification" until "transfiguration" during one's lifetime. But there are obvious problems: if sexual desire is from "the devil", why is our reproduction dependent on it? If the desire is from "God", why this "passion"? If praying works for you but not somebody else, the divine is powerless against the animalistic evil? You then enter the endless saga of strange suffering condition apologetics justifications, reality evasions and possibly even perversions, perhaps even criminal behavior encouraged by poor mental health.
It's just a normal and healthy biological necessity, thus it's not your gateway to sin, it's your gateway to adulthood and perhaps reproduction. It's universal in mammals of both sexes, including humans. Similarly to how common masturbation and oral sex is before intercourse, preliminaries, in the natural world, including humans. Other than health display and other attraction rituals part of sexual selection.
More difficult to make love? Nonsense, unless perhaps you masturbate and orgasm just before sex, but some people actually do it to relax or to last longer. In the cult I was raised in, where ironically women have less rights due to patriarchy, they claimed that masturbation would make people less respectful to women. The opposite is actually true, misogynism is even more likely in those who demonize sex.
