Man, im so glad i waited a bit longer to have sex (it was at 19). I was SO awkward at 16 and would have done it for all the wrong reasons, plus no way near mature enough. the thought makes me nauseous uuuuuugggghh.
Anyway, it happens. My boyfriend only reacts when i make a face.... and i usually do, cause it is a bit embarrassing. your in the moment and suddenly your business sounds like a baritone! Not super sexy. Anyway, my bf thinks its kinda funny, and i suppose it is. I would prefer it not to happen, but i cannot will my vagina to do what i want it to do. if i could, i would be a very happy lady!! Just remember, unless your lady parts sound like theres a demon in there (or a crying baby) i dont think he cares. He's still a teenage boy (this applies to all ages though), and he IS having regular sex. That's all that matters to men!
