Sperm safe lube?

So my husband and I usually use lube because it's so much easier for him to get there if we use it.  Since we're TTC, we got Pre-Seed but it's really difficult to use because it dries out on him so quickly.  I don't have an issue with dryness at all.  We couldn't quite get there tonight using it.  Are there other lubes, if any, anyone else had used? Any tips are welcome!
