It's very refreshing to read your thread, raushan. Fair play to you for speaking about it. Again, I have come to the forums for other reasons but quite happy to stumble upon your thread.
I've been meditating for over 5 years. Almost a year ago when I visited Dhamma Dipa in England I began to ejaculate during my sleep, I felt the energy of the place heightening the chances of it happening . It was incredibly embarrassing at first, so much that I had to leave my retreat, guilt is not a nice feeling, in Ireland we have a lot of it because of the catholic church, but it is a global issue.
I have been having these experiences since then, if I don't do it myself after a few weeks it happens in my sleep. The more it happens the more I accept it and even laugh about it sometimes. A large part of me doesn't want to watch porn because I feel it's unethical and even for a day or two after I ejaculate I feel quite strange, but perhaps it is better to do so once every week or two so I don't create that mess.
One thing I have done to lessen the possibility of it happening in my sleep is to sleep with my heading facing east. And I find that if I have a lot of strong foods like onions or chili's in my diet it is also more likely to occur.
It is a sensitive issue, and it took me some time to even talk about it. If I ejaculate so easily without being touched by another person, the likelihood of me ever having a healthy sexual relationship is quite low, I would like to have a healthy sexual relationship sometime, but somehow doubt it will be possible. It is what it is.
