Was anybody else bothered by Diego's character in the beginning ?

I liked the movie, mostly the second half, and its final message.

However, in the beginning I almost changed the TV channel, as Diego's character seemed kind of a prick and his romance with Gemma unbelievable. What bothered me most (and is the point of my question) is their first sex scene, which to me was bordering rape. I was surprised to see such a cliche about how to seduce women, probably because I had higher expectations from the movie.

Was anybody else bothered by it? I feel the romance and Diego's character could have been portrayed differently, without using such a harmful perspective (the guy's insistence, entering her room and starting to undress her even if she says no). I am curious about your opinions.
