Jordan is a very conservative country. While you are there you will probably notice that a lot of Jordanian men wear a lot of hair gel and tight clothes and hold hands walking down the street. This is not because Jordan is an open-minded place; it's because homosexuality is so far from acceptable to acknowledge in public in Jordan that men can do this without being accused of being gay. I would recommend in the strongest possible terms against making your sexuality clear to any locals who you do not explicitly know will be accepting.
When I was in Amman I wasn't looking to hang out in the gay scene much, but Books@Cafe is a place that is popular both with expats and the local gay community.
All that said, I loved my time in Jordan. Enjoy your trip!
