MMM, you don't understand the reference to 'no hair' because you didn't read the background. It's ok, you can't know everything at your age. I am glad that you ask questions as that is the way we learn.

I attached one of my memes that shows pics of actual bald feminists and I would think you might be more attracted to conservative girls. I agree if your girlfriend cut her hair, you should not disown her. You should love the girl because she is beautiful on the inside and treats you well as you obviously would her.

2. There really aren't tests for personality/compatibility...you just have to get to know the person and decide for yourself if he or she has similar ideas, goals, morals to you and if you get along, have fun, and do not argue much about things.
" Do you both want to have children?" That is an important question to ask as that could be a dealbreaker for a relationship if one of you doesn't want kids and the other one does.
Also, look for the 'spark' of attraction....if it is not there, it would be difficult to 'create it' later. If you have it, you can kindle it and it will last a lifetime.
And if you are both 'in love' and want to commit to each other and not date anyone else, you can get married and hopefully live happily ever after.
