Maybe the man could shave too. If you are the person that wants it done to them, you have to do everything possible to make the experience great. I am afraid that it can ruin a relationship. Maybe you don't have the experience or comfort level. Hopefully your partner has patience and will teach you.
Partners can be somewhat immature at times.
They need to teach you about stimulation and about how to get into it mentally. I think once people become more experienced, then things won't be so awkward. With sex you never stop learning. Accept that you are learning and don't take what partners say to heart. Hopefully you have a tolerant partner.
