Hi, Damiann. I have to agree with them. Because of my psychological conditions and because of the house I grew up in where my parents didn't love each other, I am extremely emotionally stunted. Love and sex was never important to me. On the other hand, I am a major movie geek (I have around four hundred DVDs and Blu-Rays) and escape into them frequently. Sometimes, it gets difficult to remember that it's fictitional. My wife's favorite comment to me regarding the subject is "Because it's in the script." Love, lust, sex, and best friend. All can be provided for you quickly and easily by just the right person who is quite literally waiting just for you. Bull. Love takes work and effort.
We also shouldn't mistake sex for love. A few years ago, I was a major slut. I had three girlfriends at the same time and was honestly having sex three or four times a week; each night with a different girl. Somehow, I managed not to catch something. Point being, I was mistaking sex for true love and true happiness. Sex is, in my opinion, neither of these things. At this point, I'm married to a woman who truly loves and cares for me. I haven't had sex in a couple of years and, funny thing is, I don't care. It's not that important to me.
You need to, again in my opinion, stop looking at movies, tv, websites, and even friends for your definition of true love and happiness. Look to yourself and figure out what's important for you and then take your time in finding a significant other with the same views.
Sex is many things but it's not required to survive. Don't write yourself off because its not a frequent event in your life. And definitely don't compare your own worth with others over any factors especially sex. What you truly want and need are the most important things to you or, at least, should be. Never let other people's views define you.
