Is it a good reason to leave a marriage if you are not ually satisfied?

My husband thinks we are ually different in terms of what I am willing to do ually and what he is willing to do. He says he is not satisfied because he is wanting more adventure ually. Is this a decent reason to leave a marriage? we have been together for 10 years married for 2...we make love 1 per week and orally 1 per week.
