is it normal not to have sexual feelings for the opposite sex?

I felt the same way until I met the woman whom I married. My freinds thought I was gay because I did not react to women the way they did. Not every woman needs to conquered by "men" so to speak. I mean that in the very best way possible. I liked many women, some were my freinds, that did not mean I wanted to have sex with them or had feelings for them. I have been married to my wife for 25 years now. When we met we knew we were meant for each other. I will also tell you that I did experiment with a couple of my male freinds at your age, and yes, the thought crossed my mind that maybe I was gay. To be perfectly honest, I sometimes go back down that road in my mind from time to time, and even at my age wonder if I am Bi. But when I think about living it, I know it's not Gods plan for me, despite my inner turmoil. Only you can know what part your sexuality, if its in question, will ultimately play. I would say, don't let it be a an avenue to cause you mental stress. If its meant to be, you will meet the right person when the time is right. So enjoy your life, meet women, be freinds, and see where it goes. I hope this has offered some help, and wish you the very best in your search of the answer that brings peace to your life.
