First time dating a gay guy, need some advice.

I'm a bisexual guy, and I recently met a gay guy on Tinder (long short story, I didn't know I could switch botch men and women, and I got more matches with dudes than girls, we kinda like each other and agreed to go on a date). This is the very first time I go on a date with a dude (and the first date on a very long time). I'm kind of nervous I will do or say something wrong, so I'd appreciate some advices for this date. Thanks ☺️ and sorry for my bad English.
