Nerve growth factor is shown to grow back nerves sensitivity to pain in a persons thigh. This also means that pleasure sensitivity will be increased in the penis because sensitivity in general is increased. A sensitive penis will also hurt worse as well as feel better. I'm thinking about using some because the sensitivity can be restored. However I'm scared I might be toooo sensitive and cum too quickly, etc. there needs to be a research study on animals and this may be the quick fix.
This study shows that it increased warmth sensitivity which would be good for vagina etc... http://www.ncbi.nlm.nih.gov/m/pubmed/10493751/
This link shows that it will work and mechanical sensitivity (feeling) ability increased and no abnormal pains were increased or randomly felt. Seems like this is the answer guys.
