My wife is gorgeous, but very conservative in the bedroom. She is currently like a woman from the '60s, and I want her to be more open. Again, a lot of women are unsure of how they are supposed to act sexually. They were raised with the notion that sex is dirty and dangerous and to save it for someone you love. They think they may be labeled as a whore, whereas men hope to be called a whore.
Men wear it as a badge of honor.
Maybe have a couple glasses of wine. Sexual charge, desire, or responsiveness varies by nationality, religion, ethnicity, culture, family, and location. Some cultures encourage sex and others don't. It is really hard to say that any particular culture is more sexy or responsive than another culture. America is definitely not at the top though.
