Well talking from what my girlfriend has told me, she feels amazing when she squirts (which I can usually tell anyway when I see her squirt) her clitoris feels weak and sensitive and she feels more relaxed, but I dunno if this is the same for other girls and stuff, my girlfriend seems to always feel more horny after squirting and cumming so we usually end up going a couple more rounds but yeah, to summarise, it makes her feel good, sensitive and even hornier
