"Now, after 4 months, things are starting to stir, but not usable, yet. Is there hope for me to be sexual again?"
This is a very complex problem. Cannabis certainly may be able to help you but from your question I have no idea if you are a male or female and that makes a huge difference in the way this problem is approached. If you respond with an answer, I can no longer answer your question because it will only allow me to answer one time. If you will resubmit the question with a little more detail I very likely can help you but without even knowing your gender, my response would either be very long or potentially inappropriate. Most sexual issues began between the ears. Please consider re-asking your question so I can address your question properly.
