Every guy is different. Some like it completely shaved, others appreciate a bush, it’s a very personal preference. Why don’t you try asking him what he’d like? It’s your decision, obviously, but if it doesn’t matter to you one way or the other then why not get his thoughts on it?
If you want to avoid the prickly regrowth issue, shave the same day you plan to have him go down on you. Hair really isn’t that big of a deal as long as you keep it neat and maintained! How much you want to shave is up to you and your partner’s preference.
It is nice to ask them what they like because they’re the ones down there doing the work, but it still doesn’t mean they can dictate what you do. It’s just an opinion to take into consideration. π
