"...he was interested in more than a professional relationship..."
And your point is... ? Relationships are a 2-sided affair. Often only one party is interested. You can't blame a person for that. It all depends on how the person acts when you make it clear that you are not interested. If he said "oh sorry, I'll back off" that's the end of it. ( However, you'd have to accept that you will be treated like any other colleague in terms of his time allocation in stead of having priority. Its not discrimination...family/friends normally have priority in human relationships and time allocation. Business contacts are just business contacts. They have to queue...)
"...problem of women falling as prey to their male counterparts ..."
Same issue. You can't blame a man for finding a girl attractive, as long as he understands "not interested" means "not interested" and backs off. I've found that most men keep their distance when they know they are not welcome.
"...Why ....their mentors are male?..."
In which cave were you hiding ? The females are new intrants to an industry that was largely invented and developed by males. The guy already has the skills and is willing to share them. Do you want to go back to Univac and develop an all-female industry so that you can select your tutor according to gender ?
