How long should I wait to use Viagra after using poppers?

I know that it is extremely dangerous to mix viagra (or other ED drugs) and poppers (amyl nitrate), and that one should wait for 24 hours after using viagra (to let it get out of your system) before using poppers. My question is what is the waiting period after using poppers before it is safe to use viagra? In other words, how long before the physiological effects of poppers wear off?


Why do sexual assaults happen?

I was wondering what the main reason is behind women getting sexually assaulted. Is it because of the way they dress, the way they act, or how easily tricked they are? Do girls say something provocative that entices the male to engage in sexual assault?
