I don't think it was insulting...seems like you just asked if that's how he felt, like someone objectified by the opposite sex (I don't know if I worded that right; forgive me, it's been a long day), and if he considered it an insult. When a woman is subjected to catcalls walking past a construction site, she is only one of many women who will get that treatment from those guys that day; the next woman who walks by will be catcalled as well, and the next woman, and so on; in a sense, then, these men objectify all women. That's how I see it, maybe that's how he sees it. I don't know, as I don't know him either. And what some women see as objectifying and insulting, other women may see as an ego boost (I don't know; I live in a small town where everyone knows everyone else, so construction workers are pretty respectful. I guess a guy wouldn't want to say "nice boobs" to his wife's cousin!)
In the case of the Locker Room, he might see it differently because it's (for a lack of better word) special. He may know that not every actor evokes the kind of response he does in the Locker Room. I don't know about all of you, but I don't go on the website for, say, Ben Affleck (nothing wrong with him; I'm just using him as an example) and call for a shower scene in his next movie. Maybe if we did spend all day at various websites for a million actors asking for shower scenes, then we would be objectifying all men. In this case, the attention is all for Carmine, so maybe it is flattering...just as you feel more special if that guy you like at work gives you compliments and says nice things to you alone, instead of making comments to all women at work. Then you feel just like one of the herd, and may feel like an object, as though he isn't particular and any woman would do. Maybe he sees the Locker Room for what it is...a bunch of girls having fun, no seriousness, but on the other hand, the compliments he gets here are genuine. The guys at construction sites aren't being genuine because they treat all women who walk by the same way.
Okay, I'll get off my soapbox now! I didn't mean for it to be so long, and I hope I made some sense!!
