I can't seem to actually masturbate which is really embarrassing. but whenever I try, and I'm wet, it just doesn't last. like it goes away so fast I don't have time. also I was never taught anything abt this. like when ppl say "fingering," does that mean like you're going FULLY deep inside? I don't understand how that would work, especially since the wetness doesn't last more than maybe a couple of minutes. and I'm female btw
