ugh😒

ok so i’ve been feeling and touching on myself since i was little. i didn’t really look into what i was doing until about 15-16 years old. so since then i’ve been pleasing myself by rubbing my clit & i’ll get this really good feeling out of it & that’s it. what exactly is that?? (i’m so embarrassed to be 19 asking that) smh .. i’m not a virgin though, i just haven’t had much experience before i stopped having sex with the partner i had. the point i want to get to is that i suddenly began to use my fingers inside my vagina & was to the point to where i felt like i had to pee or could that have been that i had to squirt & just couldn’t? if so, any tips on how i can go through with it? pls respond, i’d really appreciate it!!!
