I am a 25 year old 5'6" male and I never had a girlfriend. I have only had sex once in my life when I was 20 (she was 16). We both lost our virginities to each other but she never wanted a relationship with me. I was thrown in jail and have a stalking conviction on my record all because I brought her a cookie cake around 7-8 months later trying to ask her out to her prom (she was now 17 at the time).

I once tried to make a relationship happen with this one other girl, but she ended up becoming a transgender (became a dude). I can't believe I made out with her one time.

Like I said I am 25 and never had a girlfriend. I only had sex once in my life and it was back in 2015.

Not only am I short and never had a girlfriend, I also lost my career. I had to voluntarily surrender my EMT license (it was going to be revoked anyways).

I still live at home and on disability.

I also have an Autistic Spectrum Disorder and other mental health issues.

I have been hospitalized over 13 times in my lifetime, all starting from adolescence.

I have been trying to learn programming and web development for over 3 years diligently. I am still an ameatur and suck at what I do.

I cannot get ahead in life it seems in the romance or the career department.

I only want a decently attractive woman without a romantic past (meaning no previous boyfriends or romantic bonds), but I will likely remain alone because I will never find that I feel.

I am failing at life. Period.

I guess it reminds me of the young romances I missed as a teenager. If only I can wake up and be 16 again. I would change so much about myself.
High school girls are some of my favorite types of girls. I feel like I would have a better chance finding a younger girl with no baggage and no romantic history than an older one.

I have CF which is a life threatening genetic respiratory disease that cuts my lifespan in half and stops me from growing quicker. Given that, I'm quite fortunate to be only slightly below average height at 5'9", but yet I've been told I'm too short to date countless times. I've never been on a date to this day and while blaming it solely on my height is admittedly wrong, my restless work on myself seems like an act of futility for helping me find a life partner because there's nothing I can do about my height. Are short and average guys meant to be alone?
