Here's my number one dating advice: listen to your instincts. If your instincts are telling you something is off, something is not right, get out. Don't worry about hurting their feelings, making a bad impression - just leave. Don't eat, drink or take anything that compromises your thinking or judgment.
If you don't have good instincts - and too many people grew up in families where they were not safe and never learned what that feels like - then don't do anything impulsive. Wait. Go on another date (and drawing things out can be hot as hell which is a nice side benefit).
You are a dude and so probably feel that not much bad can happen to you on a date. But it is possible. I've known several bi/gay men assaulted by dates or acquaintance or partners. Listen to your instincts. I hope you have a fab time.
