Hookup Help

Okay so, I'm 18 and very new to the online dating scene. I'm a virgin by every definition of the word, I watch porn and what not of course, but I haven't ever been in a relationship, or seen another guys penis in person, or even had my first kiss. But, I finally made a grindr account earlier tonight and hit it off with this guy, who lives within walking distance, only thing is, He's twice my age, well, 32, but close enough.We've been kinda talking about me coming over tomorrow and maybe watching porn and jerking off together, I havent given him a solid answer, and I really want to, I want to step out of my shell, but I dont drive, and I'm not out to my parents, I can only think of all the things that could go wrong and I just want some advice on what to do.
