Cocoa butter smells like chocolate. You can sometimes buy pure cocoa butter in the toiletries department of the health food store. It looks like honey colored wax. It melts at body temperature. It's greasy but some people find it drying.
If I was a man, I would wear it instead of cologne. Take a little of it and put in behind your ears to something like that. I'm female, and I'm allergic to perfume so I did that for a while.
It's no substitute for confidence or knowing how to talk to women, but it could help. About 10 to 20% of the population is allergic to cologne and more people just don't like it so this might be better for that too.
If I was a man I would give cocoa butter a try. You want pure cocoa butter.
