Is it normal that i suck so badly at getting (and keeping) girls in my life

Im 27 never had a gf. I am skinny,average height, not bad looking but not super sexy or chiseled either.

Problem is despite my best efforts over many years i just SUCK. AT GETTING, GIRLS.

Ive met a lot of girls over the years and had many uncomfortable interactions. They are all a little different but i usually end up shooting myself in the foot somehow. I am too insensitive, or too uncool, or too uninteresting, or too awkward, or too inexperienced, or too arrogant, or too blah blah blah.... Sometimes it even feels like i cannot conpletely control the stupid things that i say. I will start regretting stuff i have said or done within minutes or hours even. I overthink everything and feel insecure about myself but never sure how to be truly confident which everyone says i need to be.

In the past i have tried working out, socializing more, changing my clothes, changing my mannerisms, etc. i end up with very few real dates and the ones that i do get dont make it past second or third encounter. I feel extremely inadequate as a result.

I am not technically a virgin, i have had sex and a few other brief sexual encounters, but they were all basically one or two time events. Nothing that lasted, nothing long term.

I just cant seem to get it right. And now im turning into a sad bitter depressed weak guy who lives on his own and does not have many hobbies or a social life.
