Okay...not exactly dating and totally INTJing over here but....BE DIRECT! I'm sure you like it when people are with you. Do the same! Once there was a guy that was a friend of a friend at a small get together on new year's, I was into him just sexually. I didn't want to date anyone, but I still wanted sex and he was attractive and seem like a good sexual candidate. So for the five seconds of being alone in the kitchen with him and the small amount of info I knew about him I said, " okay so I want to have sex with you. You're single I'm single. I'm not looking for a relationship and in a purely sexual sense I like all of you." Meanwhile he's open-mouthed staring at me, so I add in "just let me know. I'm down whenever" and left the kitchen. I shit you guys not it took a full ten minutes for him to even say anything to me. Which was "that was...either amazing or incredibly hot". Long story short...we've been exclusively fuck buddies for...over 4 years now when we're both single and now because of my moving...in the same state. Good luck, op!
