Everybody's different. While most people within reproductive age require some level of attractiveness that they like, that's not everybody's truth. Other people are more interested in intelligence, humor, money, body shape, supportively, etc. I have noticed the older people get, the less physical attractiveness seems to matter. They seem to focus more on companionship, health, and financial independence. Then again, most of the older women I know aren't really interested in finding a partner. They all say if it happens, great; if not, great. They're happy either way.
That being said, my comment used a lot of "I''s" because I can only speak for myself. Once *** is no big deal, I'm sure I'll only be interested in a guy's mind too. Right now, I'm interested in brains and beauty.
