Sleeping with a coworker

I’m newly single and have not had sex since last year. I have a younger coworker that I am attracted to. He is always inviting me over for drinks at his place. We have a common friend that he also lives with, so she is an excuse to go over. I have not had sex since last year and I got needs. I was hoping his transfer was going to get approved but it did not. I am also hoping to hear from another company. I don’t want to marry him or have babies. I just want sex and to feel wanted what do I do?
