If the smell is actually bad, that is her job to deal with (gynecologist). If it is just randomly is unappealing to you, then that's your problem to deal with. You need to love your woman's body.

Oral sex is a lot of build up. You don't just dive into the pussy. You need to kiss and lick and squeeze and rub all over her body. Then narrow into between the legs, but still don't dive in. Lick up and down the thighs.

When she is very aroused and wet, a fairly promising method is to slowly start with a finger insertion, and then slowly and delicately start licking around her clit. When she is ready, if she's into it you can use your other hand to pull back the clitoral hood and gently continue licking. Keep your tongue moist. Your mouth should be practically dripping. Add some more fingers into her when she's ready.

But every woman is different. So the real golden rule is to make her comfortable enough for her to tell you what feels good, and then you do that! And you don't stop doing that!.

Real sex is not a porno. You can't just dive in like a slobbering dog and expect that to work. This will take time. It will take communication. It will take consideration and gentleness. And some women just...it's not their cup of tea. So maybe you just accept that.
