Help! What makes sperm taste better?

So my boyfriend is tested to be clean, but he's a smoker and he does enjoy his alcohol. He adores coming on/in my mouth, and I enjoy that too, but the problem is that the smell alone is so revolting to me, and I'm not even mentioning the taste. I always swallow, but I really need to compose myself to not gag. Please help, is there any way to make the taste/smell better? I've heard about pineapple, but when should he eat that to work and is it actually effective? Are there any other things I could sneak into his dinner? 😇🍍💃🏼
