Okay, this might sound weird, but hear me out - dick musk.
You know that dick-y smell when you take you take your thumb and index finger and go around the glans of the penis (sorry cutfags), the musky, a bit urine-y kind? It's an aphrodiziac basically.
You take your fingers, go around the glans of your penis and apply it to your neck and under the palms like cologne/perfume. I've had lots of women give me bedrooms eyes because of this.
