Indeed, there is a danger in inproper suppression of lust. Thanks for the warnings and support. I also want to send my support to everybody who wants to try this.
But there is also danger in lust, and there is a skillful way to deal with it, following the dhamma. Whatever this skillful way is, is best found through both referring to suttas and teachers, but also by just trying, I think. It is probably different for everybody, with different minds with different attachments, at different stages of the practice, so we have to determine the best way for ourselves. We're all different.
Some may be at comfort with their current sexual activity/feelings, and others are not. For those who are not, I think it is not about becoming at comfort with it, but about changing it. To overcome an attachment, one shouldn't be comfortable with it; one should recognize it, see how it is uncomfortable (dukkha) to oneself and try to abandon it skillfully.
