I am not okay with my husband’s masturbation habits

This is not a topic I would venture into with anyone and I am doing it here as people remain anonymous. I hope there is someone who can offer some advice on this. My husband and I have been married for years, we still love each other and have a great relationship. Sex wise we are also pretty active. There is just one aspect that’s disturbing me, his masturbation and this has been bothering me a lot and the odds are against me. I know all guys masturbate and he masturbated before marriage but I am not comfortable with his excessive masturbation in our married life.
