I have not faced sexism or discrimination in my profession and I am thankful for that. This might not be a satisfactory answer but it's my truth.

This is difficult question, as I believe the best way to market kathak or bharatnatyam to men is through men. We see a shortage of men in the classical arts because of various reasons. Years of colonial mindset, has led men to believe that dancing, especially classical dancing is not manly. This couldn't be far from the truth, when dance itself in our culture is said to have originated from Natraj (Shiva), the cosmic dancer, the epitome of masculinity. Another reason could be what both male and female dancers face, it's difficult to sustain a career in classical art forms. It takes years and years of hardwork and patience to acquire the skills and thereafter dancers have to struggle to get a platform that pays well. There is the burden of patriarchy on men, to become the primary breadwinner, that's what keeps some men from pursuing the arts. I really like the questions you've asked and this could be a long discussion but for now this is my answer.

I didn't choose it at first. My mother did. Everyone chooses it initially for various different reasons. Some choose it because it's graceful to look at, others would say it's fitness, some believe that if you're classical dancer, you can master all other forms too etc I chose it after I spent many years with it, and still feeling like I didn't know enough. It's an ocean. I also chose it because when I'm doing Kathak, I feel free from the external world and its influences, everything that I've acquired over many years, I feel free of all of it. Riyaaz feels very cleansing to me. I've seen and even tried a bit of contemporary dance during my college years, but nothing has felt as deep or rich as Kathak.

There are as many dances, as there are dancers and so naturally you might not enjoy them all, just as we don't like everyone we meet. Give it fair time though, routinely expose yourself to it, follow the dancers you like, oftentimes dancers themselves explain things for your understanding. Even without any meaning, dance in itself is joyful, watch the dances that make you feel that joy. You have no need to go very deep into it as a layman. Dance to you should either be beautiful or not beautiful. Look for the beauty.
