Lubricant

So I need help. We it comes to sex I get natural lubricated but it doesn’t last long and I get dry quick. (Happened last night) so I was wondering what is a good lube for me to use for me and my partner? Plus I’ve never done anal before but once my partner pokes me it does hurt…. So what is a good lubricant for me and my partner, use for anal sex, won’t be sticky or cause irritation along with keeping my Ph balance safe. So please can anyone help me 🙏🏽🙏🏽.

Another question… can I place the lube on my genitalia dry or wet ?
