and regarding the idea of chemically putting an end to your sexual need forcibly is so crazy like something from a sci-fi movie
I cant see how that can be considered "crazy" , i see that more as a solution .
if you cant afford marriage due to financial instability,disability or any other reason as Prophet Muhammad (PBUH) said "he who cant afford marriage should fast " .So the person should fast and as the same time use these medicines to suppress any desire that may come.
