The range of sexual activities with which hypnosis can be used is basically all of them. Hypnosis isn't a sexual activity itself, but instead it can be used to:
- Decrease inhibitions,
- Increase sexual sensitivity and responsiveness,
- Improve the experience of fantasies, and
- Add variety and intensity to sexual activities.
Hypnosis isn't a solution for sexual problems. If your partner can't get an erection, has problems lubricating, or orgasms way too early, then a visit to the doctor is probably in order rather than experiments with hypnosis.
On the other hand, if you've got a good sex life with your partner and you'd like penetration to maybe feel more intense, or you and your partner think it'd be exciting if you could make her do a striptease whenever you wanted, or if you'd to explore some intense sexual fantasies together, then hypnosis could be a way to go.
