I wouldn't know; either would most women. It's not like we don't experience spontaneous sexual desire. We do; some of us, frequently.
It really does come down to respect for someone else's body. It's not that hard a concept to wrap one's head around.
For one, I don't feel compelled by social narrative to pursue or engage with every sexual impulse or feeling. Therefore, I can acknowledge it, internally, and go about my day. There is no shame in having these impulses or finding someone sexually attractive or alluring. It's just a feeling. We're humans. We're swamped in feelings of all sorts all day. Our feelings are like cilia that help us navigate within the larger body of humanity (tribes and civilizations). Why hold shame about something so evolutionarily advantageous. It's like saying you hate having the opposable thumb.
My opinion, the biggest problem men have with sex is respect both the act itself and within themselves. It's one thing I often find missing in articles like these. Respecting women's bodies would be a natural offshoot of respecting sex itself and respecting your sexual self.
Men are trapped between dual notions from the 19th century that are incongruent with a healthy sexual life: Maslow's hierarchy of needs and the idea have no inherent worth because the reproductive worth of sperm is so low. The whole "spread your seed" ideology.
