how long did you last for?
less than 1 min - well you need more practise edge your self and hold that edge and hold it for at least 2 mins if you cum you have to try again
1-3 mins - well you can hold it at lease but not for long enough take some of the cum you spilled on your finger and put that finger up your ass then suck your finger clean
3-4 mins - you nearly had it oh well slap your cock 20 times hard
just under 5 mins (no more than 20 secs out) - almost had it click continue
over 5 mins - well done you may rest for up to 5 mins
