>>20327283that guy in the OP isnt 10 cm though.
Looks more like 6-5 cm.
Look at lesbian porn bro those girls make each other cum with their little tiny fingers all the time compare their fingers with your cock and you are huge.
I am 12 cm and never had a problem, the g spot is around 5-6 cm inside the vagina anyway and like half of women cant cum from penetration.
You just denied yourself the pleasure of life for nothing except your own delusion.
