I'm 56, have always had a VERY strong sex drive, I have Viagra & LaVitra but get disappointed that I HAVE to take those to make sure I maintain my full erection through the end of cumming with my lover. Is there something else I can get access to help me with this unfortunate situation so I don't have to experience the ridiculous side effects from the famous drugs? Do share any info & anyone else out there that has the same situation. Any help??
