As a long term Tumblr User who amassed over 40K followers over various blogs, I can give you a view of pages I follow, share their pics and ones that I wish I could but pass.
If you want followers, to share your own content and for followers to share your content, Use the like feature for the Black and White Sex Gifs. Blogs where a sexy girl posts 1 picture and 10 sex gifs are the ones I cannot follow. I'd love to see your personal pics and reblog them. But I can't fill my feed with your sexual fantasies.
If your just on here to post things that you find sexy, that is perfectly cool.
I'm just pointing out that for people who try to reblog a lot of original content, it is basically a deal breaker to follow people who post tons of random sex posts and 1 pic of themselves here and there.
A blog with all original content is easy to follow. A blog with 10 random pics / gifs with some original content sprinkled in makes me pass.
Not hating or anything. Just pointing out a perspective you may have not thought of.
I personally Like pics that I like to "Use" Later :) That way my followers don't have to see them and I can access them whenever I want.
