I've worked with men like this
Being a chap, I notice when men are letching around women in the office, but strangely enough not all women realise this.

If I comment on "how creepy was that?" they often reply "What? Oh he's just being friendly.". Yeah, right.

I can sympathise with you, not from experience to myself, but having seen first hand how even "normal" men treat women at times.
