Seen guys creep out their female teammates both as a student and observed it as a mentor. I think the hardest part of addressing the issue is this: should we be proactive and ask female students if another student is making them uncomfortable, or, should we be reactive and wait for students to come to us with these issues.
What I personally have seen is that some girls are sometimes hesitant to talk to someone about this, especially if all mentors are male. I have always tried to be as open as possible to my students about these types of situations, and so far it has worked well for the students i have helped, but I think the hesitation will still be there if all mentors aren't working towards making their students feel comfortable in all situations.
In college, the women in engineering classes are notoriously hounded because there are fewer of them already, so it probably makes the entire cycle worse.
I don't think a solution exists unless you proactively discuss this type of stuff with your entire team and their parents before each season.
I hope there aren't many examples of such behavior.
