Problems getting "wet."

I'm almost 22 years old and my SO and I have been ttc for almost 7 months now. It seems like ever since we started ttc, I have had problems getting wet and I stay pretty dry down there. Could this be contributing to not getting pregnant? Is this normal at my age? We really want a baby and I'm just wondering if it's my fault why we haven't gotten that BFP yet. 😕 Any advice or recommendations? We have tried Pre-Seed but he didn't particularly like the residue that it leaves behind.
