Questions: Relationships

I have never understood the point of marriage if the woman isn't a virgin. I mean the idea of marriage is that you have a woman for yourself, and no one else can touch her. But if she is not a virgin, then that means somebody already did that before.
And that person did it without any commitment towards her. If someone can do that to a woman without any commitment then why would a man commit to her and want her to be his wife? And besides that, wouldn't it irritate you to know that another man had touched your woman? I don't know, I hear some people say that they are fine with it but I don't know if its just a politically correct front or if they actually mean that. I think we men should be a lot more honest about our thoughts and feelings.

For those who are unfamiliar with what a hair fetish is: basically people who have this enjoy playing with long hair or in some cases enjoy cutting it, whether this be just a little bit or a lot. I am asking this question bc not a lot of people have this fetish and I am afraid to tell my girlfriend about it. She lets me touch her hair but I would enjoy brushing it, playing with it, and occasionally trimming it. However, I am afraid that she would find this to be weird and that she would break up with me. I've liked to play with long hair since I was about 3 years old, so it’s not going away. I always felt like this was a weird fetish to have, especially since only 7% of the world has it, and I’ve tried to “cure” myself of it but every attempt has failed. If you think this is weird, that’s ok, I’ve accepted it; I just don’t want my girlfriend to leave because of it. If that’s the case, then I will just continue to hide it like I have for years.
