viagra
 

I've been using 1/4 of 100mg Viagra with excellent & long-lasting erectile results. My face, lips and even my scalp flush temporarily about 30 minutes after I take it. Does anyone share my impression that Viagra also provides endurance and significantly delays ejaculation which ultimately is achieved with extended and pleasurable effort :) !

Yes, anorgasmia (delayed orgasm or inability to achieve it altogether) is a known side effect of these drugs.
