Never worry about a girls feelings in bed if you cum in 5 seconds whocares you got off heres the time line.
She gives you head: est time 7mins 40 secs
Put on rubber: 8 secs
You cum: 6 secs
Putting your close back on: 1 min 14 secs
Taking ten bucks out of her purse for gas: 12 secs
Remember the whole act of sex should never last more then 10 mins and should always be about you and never her.
