Is NOBODY wrong in the post ? POST : So long story as short as I can make it...

My husband is on antidepressants which makes it hard for him to "finish". Not hard for him to get hard at all just finishing is a problem. I cannot and will not speak for anyone else but for me, I'm kind of a "quickie" person. No marathon sex situations for me, at least. I just am pretty much done, orgasm or not, with penetration if it's more than like 15 minutes or so... but he can go for much much longer because of his medication. 

Am I the asshole for asking him to start himself off and get to a "good" point before joining? (Also I should add that we both want to have a child so him finishing is kind of something that is necessary)
