Go out and get a copy of "The Multi-Orgasmic Man" by Mantak Chia and Douglas Abrams. Read it first, and then give it to your boyfriend to read. It's a fabulous book on tantra for the typical American guy who wants to have better control over his erections and ejaculation. It's a step-by-step manual written very clearly. If he has difficulty with any of the techniques, I can work with him by phone.
