My boyfriend can never get me to orgasm and he gets so close but cant hold off till i orgasm or gets exhausted because i take to long what can he do to make me reach my peak

The most important technique for him is PC muscle relaxation. Get him to read this and all the other orgasm control techniques. Tell him to practice on his own first, then with you.
This will help him to last as long as he wants.
The second step is to read all about the clitoris and the g-spot. If you or your boyfriend practice stroking your clit there's a good chance you'll have an orgasm.
