I want to get my roommate a nice prostate massager/stimulator https://top10sextoys.com/toys-for-men/ something or some other kind of anal toy for his birthday. His birthday isn't until spring, but I want to have a toy picked out so I can save up for one and order early.
Anyway, although I myself enjoy anal, I know nothing about the specs for anal toys, especially not anal toys for men. He's never had a toy before, but he does enjoy anal, so he's a beginner to toys, but not a beginner overall.
What kind of specs should I be looking for? Also, if anyone has any toy recommendations with a max price tag of $40, the help would be greatly appreciated.
