New Sex Positions?

I feel like I need help in this department. We do the same positions every night. Missionary, I ride him, sideways, on my stomach and doggy. Don't get me wrong I fucking LOVE them but I want to do more for him because he's always the one pounding me lol. I hate reverse cowgirl it makes me feel gross so besides that, what else can I do? I do give him a lot of bj's but I just want to spice it up.
