My ex used to really perve at other women when he was with me and that bothered me, i dont care if he looks, but drooling and carrying on is completely different.
I would look at men myself but not in the obvious way he would.
The other thing he did that annoyed me was beeping at MEN and whistling making it look like it was me and then turning around and saying to me "what are u doing? i thought u were with me"
i laughed at first and found it funny afterwards it got down right annoying.
