Guilty Feeling/Random Uncomfortable Thoughts

Hey so uhm I’ve never been able to finish masturbating like, ever?? I tend to stop because while I’m doing it, I either feel guilty/feel like I could be using this time to do other things. I also stop cause my brain will have multiple thoughts going through my head, whether I’m thinking about random people I’ve interacted with (who I’m not attracted to btw, I mean sometimes it is someone who I find attractive but mostly it’s like a friend or a celebrity that I fangirl over which makes me really uncomfy) or a song that was stuck in my head starts playing and it’s like a wholesome song or a song my friend was singing and therefore I’m hearing their voice so I just stop cause I get super uncomfortable?? Like two minutes ago I was hella horny fantasizing about stuff while watching porn and then my brain just goes “how about no ❤️” and starts making me think of things I don’t want to be thinking of.

I also don’t really know if I’ve ever had an orgasm either like sometimes I’ll just stop feeling whatever I’m doing or the previous thing happens and uh yeah. So uhm- does this happen to anyone else?
