eyes open or closed

Ladies when u give a guy head, do you usually keep your eyes open or closed? I used to give my ex boyfriend head and my hair would be in the way so he couldn't see me (that's how I'd prefer it) but now this new guy I'm talking to asked me if he can watch me give him head and also requested that my hair be up in a bun while I do it...... what do I do? Keep my eyes open? Closed? Make eye contact? Helppppp LOL
