I have as of late been experiencing a few problems in the bedroom (maintaining erection and delaying orgasm/ejaculation). Though I'm not in my best possible shape or level of fitness, I am reasonably confident that my problem isn't a physiological one. The other day, my girlfriend and I became intimate after I spent about 20 minutes in meditation followed by a brief recitation of the Guan Yin chapter of the Lotus Sutra. That night, I was able to perform splendidly, bringing my girlfriend to satisfying peaks of pleasure. Yesterday brought another story. I spent 15 minutes pleasuring her orally so as to prepare her for penetration; yet, I was only able to last for about 5 minutes of continuous thrusting (embarrassing I know). Would you guys be able to recommend any simple practices to increase one's sexual vitality or longevity? Meditation and disciplining my mind is obviously at the top of my list of remedies, but I thought I would pose the question to the community for additional resources/suggetions. I didn't have a wealth of time to make this post, so I will have to add details later. Feel free to ask for any piece of information you think might aid you in your diagnoses however.
Thank you.
