i don't know if there's something wrong with me, i got my first boyfriend this year, whenever we try to have sex he can't fit. is there away to fix this? i get so wet but it still won't fit. i'm worried that im too tight. this is my first post on reddit, i don't really know how the app works but im so desperate for advice that i downloaded it. should we use lube? if so what's the best type of lube for it. please help!
