A tantra course did a lot of good for me, more than any book ever could, but I'm slightly reluctant to recommend because a lot of things can hide under the name "tantra" and also different people prefer different approaches. In my case it was roughly 15 evenings (I prefer that over taking a weekend or an intensive week as it's often organized) in a group, where the meeting usually involved some quick dance and communication exercises to get relaxed and tuned in with the group, some meditation/energy work from various traditions, and some conscious erotics such as touch, nudity, rituals. (The level of involvement is voluntary, participants are tought and encouraged to watch their boundaries.) Overall it has helped me reflect and taught me to use sexuality as a tool for self-development and spirituality if desired.I need advice on overcoming sexual insecurities and becoming comfortable with my sexuality. Books, articles, personal experience? I'm 45. I don't want to hide in my shell any more!
