I think it was moving. Thank you to those that have pointed out how he seemed to think that beauty was a choice, I hadn't noticed that. Re - how annoying it is that a man raises an issue and the world listens: I agree with that generally but I feel that is not so relevant in this case as the realisation of the message is uniquely tied to the fact that it was realised by a man from a woman's unique perspective and that this particular message is not something that men can usually experience, realise or relate to (because they are not women.)
I also think it is was moving because he realises that he has missed out on the companionship of women (rather than flirting/dating).
Re the scene where he boldly asks her to go to bed with him as that is what she has told her "female" friend she wants a man to do - but he is, of course, rejected. I like that scene because, as well as being very funny, it also shows that, fundamentally, he cannot really understand what it is to be a woman because he has not "lived" long enough as one. He missed the subltety and humour in what she was saying to her "female" friend and took it literally.
