Genuinely asking, but would any heterosexual man actually be upset if a woman made sexual advances toward them?
Almost every straight guy I know would just view such a scenario as "suprise sex."
Unless David Hallard is homosexual, I'm going to assume his harasser was a man.
During my time at University I became friendly with a woman who was quite a bit older than me, having moved away from my home city, I didn't have many friends so I was very thankful for the few people who became friendly with me. I was invited to her house and rather naively I accepted the offer, it was very clear it was just a friend situation, I had no interest in this person in any capacity, as I say - it was just friendship.
I went, and during the evening i had a couple of drinks she'd given me, unbeknownst to me some kind of drug had been put into it. I know things like this are a sensitive subject, so i won't go into detail, but needless to say, the events of that evening have scarred me for a long time, and it's been a daily process of getting though it.
Comments like the one in this post are incredibly harmful. "Friends" of mine during this time made similar, and it made me feel even more ashamed than I did previously. So in answer to your question, yes - this can happen to heterosexual men. It has nothing to do with just wanting it "because you're a man" or being gay or straight. Think about your words before you post.
