First off, thank you for the Ask.
On the Dom question, this is a question I get often. How to find a guy that is not a total shitbag. A lot of people say don’t find people on Tumblr; why? People are open and honest because they have anonymity here, so you get a side of people they are afraid to show elsewhere.
Granted, you have to be smart enough to know they are showing you only one side, so when you get to know them, listen to your inner voice. If I were single, I’d trust here over Tinder or Match or some dating site.
But the same criteria you have for men in general should apply. Are they nice? Do they have a good job? Do the have patience? Stuff like that.
