What has been your experience with ED medication(s)?

OK men I am also a man and I am over 40 and as there are some things that come with age that we love. There are also some things that come with age that we don’t love. Like our erections either not happening at all or, in my case just not getting as “upright” as they once did. Anyway, I am just wondering if other guys out there who have tried or regularly use Viagra/sildenafil, Cialis /tadalafil; have or do you experience those sometimes embarrassing spontaneous erections like we used to get when we were in HS and/or college?? I tried it and it definitely worked as I’d hoped, however; the next 24-36 hours that happened more than once in settings/situations where it was not welcomed. My question is: does/has this happened to any of you guys after having taken the Viagra or sildenafil??
