makes sense with everything you said however these products you would be taking are not life threatening, any type of dermatitis can be a b*tch. ive worked with kids who had major issues, its a shame.
As far as application goes NO do not apply anywhere near your junk!!!! bad idea
however you will apply to think skin, such as upper chest, forearms shoulders traps and wrists. also places without hair such as inner thigh (not by your junk) can work too. you definitely will need to cycle dermacrine. I have seen 8 week cycles but maybe see how you feel on 4 at first, also like I said maybe get a product such as viron or anything with longjack/tongkat/boron
that was a killer combo for my libido
