Swallowing

So me and my guy have been sexually active for quite a while now and it’s been great. We have been together for 5 months and started becoming sexually active 2 months ago. But we have tried a lot of stuff out including him licking me out. But the other day he mentioned about me swallowing becuase he licks me out. And I’ve tried it once and I absolutely hated the taste. So I was wondering if anyone had any tips to make it a little bit better or any tricks to make the taste a bit better ? I would really appreciate with his birthday coming up I would like to give him a surprise.
