Well from what you described, I wouldn't say that you have a low libido. It's about average for many couples that have been together for a long time. IMHO, a good example of low libido would be if Jen asked you whether you wanted sex or pizza and you callously replied that either one is fine! A single person would go straight for sex with a partner - Pizza is what some singles would have for dinner on an average night!
It doesn't look like he took any action against your account (I can still see all of your comments on his dA! page - They are not marked "HIDDEN BY OWNER" [of the dA! page]). The worse that he could do by himself officially is
block you from his page. The average dA! user cannot
ban users from dA! - Only dA! admins can do that and only if it is warranted. You were trying to make your point across in an intelligent manner but again, dA! allows any user to block any one from their dA! page for any reason that the users sees fit (DA! says that it "Helps to cut down on spam and to facilitate the most efficient usage of their system").
