Lubricant when TTC

So what do you do for lube? I know of Pre-seed but I can't get that here (in Guatemala) and I can't BD without lube. So I googled what is safe when TTC and saw olive oil is good. Hubby and I tried it today and OH MY GOSH it was amazing. (Sorry? lol) it was so much better than any lube we've ever used. Just a tiny bit makes soooo much difference!
