Yes, it is normal for penises to have their own scent, just because people's bodies can have unique scents. Even if the scent is normal, it doesn't mean that you have to like it personally. I can't say for sure if your partner's scent is concerning, so I have a few questions:
- Has the scent always been the same, or is this a recent change?
- Have you noticed the scent being better after your partner takes a bath?
- Aside from this issue, are you satisfied with your sex life together? Is there anything you would like to change?
