just add more foreplay, lick that pussy till she is ready to blow, then finish her off. doesnt matter how as long as she enjoys it, you can work it out so it isnt a problem
There are lots of things you can do. For starters, try the "stop-start" technique--the basic idea is that you start having sex and then stop as soon as you feel an orgasm is about to happen. Wait until the feeling goes away, then start again. You'll gain better control of your orgasm the more you do this. Another possibility is to try condoms with a numbing gel on the inside. That will dull the sensations and allow you to last longer. If these things don't work, you may want to talk to a doctor or sex therapist about other options.
