Tired of men & casual relationships!!

So I have been trying to find a boyfriend for quite a while now. It’s not that I don’t get any response from the apps but it’s about the requests for having hookups and casual relationships. Can’t believe that people don’t want to enter a serious relationship! Part of this problem is that I look very attractive. I understand that sex is an important part of a relationship but I can’t understand why it’s the reason for entering a relationship. Does this mean that I am weird?
