I'm going to try to unfuck myself for the next few years and stop being a degenerate porn addicted loser piece of shit and hopefully get a girlfriend (never had one before).
That got me thinking that I don't actually know what to do with a woman outside of sex.
My hobbies consist of firearms, hunting, lifting weights, muay thai, reading books. As you can see none of these are really things that can be done with your girl.
So what am I supposed to do with her to keep her interested and not get bored? I don't watch movies, consume social media, enjoy social events or mass gatherings.
How old are you? This is important because past a certain point, with your admitted nonexistent experience with women, it would be best to focus on other things.
A truly good, beautiful woman is well worth the pursuit. Pussy, such as it generally is these days, is not. I say this as a man who has a great deal of experience with women, 40 years old, who has been celibate the last several years BY CHOICE. Opportunities abound yet I refrain from indulging specifically because I don't want any more frivolous physical encounters, nor the screeching of females I do not care about.
For me, either I find a magnificent Aryan woman to be my bride & bear my children.... or I live a ascetic crusader life until I breathe my last. While I would prefer the former, I am content with the latter.
Based on your post the best course of action is to unfuck yourself first and foremost. Being a "degenerate porn addicted loser piece of shit" is a choice, not some malady that happened upon you without your awareness. Either sort that first, or be a slave to vice.
