I (F) would like to get my partner (M) an Aneros as a gift for Valentine’s Day. He’s never had an anal toy before but he loves getting his ass fingered during head. I know he sometimes also fingers his own ass while jerking off. What would be a good starter model for him that he could enjoy solo but also use during sex (if I’m on top)? As I said he’s never had anything wider than a finger in his ass so I think something more slender would be a good starting point.
