<human>: Can you provide a brief rundown of the text in within 3 sentences?

The first time it was just generally creepy and forward flirting, the second time a coworker dragged his finger down her cleavage. She was clearly disgusted and anyone looking would have been able to tell that it was unwanted, but at these things people are generally drunk + whatever else they're on. Both times it was older males that have been at the company a really long time (whereas she has only been here a year or so). 

I really want to bring this up to our company's president directly. It's not an isolated issue, I've talked with two other women who have been bullied by older men at the agency, sexually and/or sexist-ly. As a man I am both a little awkward about bringing this up (since I'm less qualified from personal experience) but also maybe in a good position since I can't be dismissed. Not that I think that's going to be an issue, as the president of the company is a woman (mid-forties I'm guessing, not that it matters).

I'd really like some advice on how to talk about this, any landmines to avoid, and generally how to be sensitive to bringing this up both as an employee and as a man. I intend on not using anyone's names on either side, but mainly making a case for a candid conversation among leadership to make sure this doesn't happen (what I really don't want is witch-hunting or a company-wide speech or seminar or whatever). Because there's definitely an MO and I doubt these guys would respond to that kind of thing. Really I just want to work in a place that respects women, and where women don't feel like it's just "part of being a woman" because that's bullshit and I hate it.
<bot>: Have witnessed/discussed multiple accounts of sexual harassment and sexist behavior from older men at my workplace and would like advice on bringing it up with the company's leadership.*
