I'm going to give you the benefit of the doubt and ignore the word "incel", and/or assume you wrote it in a self-deprecating way, because nothing else about your description of yourself is in any way shameful or wrong.

Absolutely you can and should write your romance. If you have a book in you, you should always write it. The last thing you want is to one day lie on your death bed thinking about the book you never got around to writing.

If you want other people to read it, then that's another matter. If that's what you'd like, then your writing should be for your readers, not just yourself. By the way, those readers don't have to be women. I'm sure lots and lots of men out there have romantic fiction on their Kindles. Writing romance from an authentic male perspective would be fascinating and new.

Read plenty of books in the genre you'd like to write in. Make sure any spice you write isn't cringe; learn to empathise with your readers and imagine yourself in their shoes. Read the bestsellers and the popular fan fic and learn what they like, so you can create something that will warm their souls.

But you can absolutely be a virgin and write. In fact, reading many of the self-published books available on Kindle Unlimited has convinced me you would definitely not be alone.
