Lube alternatives suggestions

Dianna
So for better or for worse, 9 times out of 10 when having sex my dh and I need to use lube. We were able to do it once or twice without it but it's not often. My question is, where I live I have not been able to find lubes like Preseed that are made to assist in conception. What are other alternatives people use in order to try to conceive?
