What tips to give to fiance on eating me out

Hello all! My fiance has tried going down on me to eat me out and stuff, but I get so much pleasure from it 🙁. I mean, it feels nice, but not enough to satisfy my sexual tensions. He has tried to lick and suck on my clit, and put his tongue in my vagina. We tried like maybe 4 to 7 times over our 6 yrs of relationship. I never really felt pleasure from it. To be fair, he didn't spend too long on eating me out, prob like 3 to 5 min and then I tell him we can stop bc I don't want to waste his time on something that's not really giving me pleasure. Meanwhile I give him really good blowjobs and handjobs 😒.

I recently read another girl's sex experience here on eve on getting eaten out and how good it felt. I was wanting to give it another try again, but idk. I was hoping maybe you guys can tell me what works for you guys so that I can try to lead my fiance to try the same things to see if that would give me some pleasure.
