Preseed

Mar

I keep seeing preseed mentioned and was wondering what it was all about. What i seem to be able to make out is that it is a sperm freindly lube? Does it do anything to promote geting pregnant besides just being a lube that doesnt kill sperm?. We dont use lube of any kind so wondering if we should try it or skip it. Is it like traditional lube where it helps moisten things up or does it help the sperms move better?
