Want to cheat due no sex from Husband

I am pretty bugged as i am clearly the one with higher sex drive in our relationship. My husband doesnt really show much enthusiasm which doesnt make me feel desirable or i feel the attention. We have been married only for 6 months now and it upsets me to think that he isnt active for sex whereas i crave for it atleast 2- 3 times a week. We do it probably once in 10 days; have addressed this matter to him many a time but no change. He says it should happen when it happens. Wanting something badly and not getting it is annoying. This has pushed me to the extent to thinking of cheating which i have never done before. Its upsetting and disturbing our relationship. What am i to do?
