Me and my boyfriend want to try and do the 69 position but I avoid it and tell him I'm to embarrassed to sit in his face (which he tells me doesn't make any sense since we have been having sex for a year and a half, lots of positions and oral sex included).

Have you got any tips for a beginner like me?

By the way, my boyfriend never pressures me into doing anything, I want to try it but i just don't know where to start.
