Question about PreSeed lube

Kathy
Hi ladies! 
I purchased PreSeed and I have a couple questions. Do I have to insert it in me for it to work? Or can we just use it as normal lube? It's so unsexy--and almost stressful- to prepare before intercourse! Keep me in your prayers-I only have one ovary, one Fallopian tube, and that ovary has a cyst on it. :( has anyone gotten pregnant with similar conditions? Xo
