<human>: Can you condense the text into a few key points?

On a throwaway because my older brother knows my reddit name and I just rather not go there.

I'm going to be alone forever. 

Before people start chiming in and telling me that I'm going to find the right one and it's all going to be okay and whatever, let me explain why. 

I purposely don't engage in relationships. As a lesbian, I've had girls ask me out but I smile and decline. I know I'll let them down. I can't orgasm or feel any sort of sexual pleasure. Sex is too important to a relationship for me and my partner not to be having any. And I know that no one in their right mind is going to be okay with a sexless relationship. So, before I start to like someone too much, I cut it off and remind myself why it's not possible. I won't waste their time.

I'm a successful woman. I have my degree in Petroleum Engineering and make very good money, drive a nice car, have a nice apartment in a nice city. I'm a happy person 95% of the time because of my friends and family and other things.

But sometimes it weighs on me like a stone that I don't have a girlfriend or really anyone who loves me in a romantic way. 3 of my friends are married, 1 is engaged and the other 4 are in relationships. And then there's me who can't have a relationship because of something that I can't control, something that should be so meaningless but is so important to healthy relationships, I just..

It's amazing how I can feel fine all day, talking and laughing with my coworkers but when I'm sitting by myself in my empty apartment, watching a soap opera or whatever happens to be on TV, it hits me and I start crying. I thought it would go away with time but it's been several months since I made the decision to be relationshipless and it still hurts.
<bot>: Can't orgasm or feel sexual pleasure, decided to not engage in romantic relationships because it's a waste of time, still feel like shit about it.
