Is it normal that I don't develop crushes anymore..?

thanks for your comment :) much appreciated, I'm only 19 so i dunno... It doesn't bother me too much but I do think about it and it kinda concerns me about my future. It bothers others more than it does me to be honest. People are quite judgmental when it comes to this are and I don't like being judged. They think and jump to the conclusion that somethings wrong with me or i'm weird cause I don't have a bf and I find it soo irritating and makes me fell bad :/
