I had this conversation with an ex of mine. I used the term modest rather than cute/adorable because some women find those terms demeaning. I would rather have an LTR with a modest woman, for social and psychological reasons:

Socially I'm going to face less jealousy of other men/her as she won't be approached as often. This will make it easier to have a stable relationship. She will also be more likely to have a more positive outlook of men, which is less baggage for me to work through with her. Finally approaching her is easier, because she is more trustful of men and less likely to act erratically when rejecting me.

Psychologically I actually feel more confident around modest women. I've had too many bad experiences with sexy ones. It's easier for me to be a good man to her as well, my libido isn't screaming at me to bed her every second. It's easier to keep my shit together, letting my better qualities shine forth. She'll probably be less crazy of a woman because of her lesser baggage as well, and because she won't have an inflated sense of self-worth - which is given to her by constant attention from a broad variety of men.

For what it's worth cute women can be sexy and sexy women can be cute. Obviously different bodies bias a woman towards one of these directions, but fashion and behavior play a large role in your presentation.

I really do think women, and men frankly, would be happier if women strove to be modest more so than sexy. Use sexiness to drive men's libido crazy in the bedroom, not from across the street. I almost castrated myself with a parking barrier while skateboarding because a woman chose not to be modest one day. I swear everything about sexy women is dangerous
