I CANT CUM AT ALL‼️‼️

so i’ve been masturbating (clitoral stimulation most of the time) for almost 5 years and i have yet to cum. i try so hard to get myself to, but it never happens. i’ve gone through at least 7 vibrators, trying to find one that could possibly do the trick, but no luck😞. i’m more than happy with the way i do things now, but i just wanna experience cumming. whenever i have sex, i’m always asked why i can’t cum and i just have to say “this is about you right now, i wanna focus on you” even though i deep down wanna feel just as much pleasure as him. if anyone has any suggestions or can connect with me on this, that would be awesome! thank you😃
