Two time F1 rejection. Can I apply for F2 in next try??

I am married and my husband has F1 visa. I am rejected twice for F1 visa. I want to go for F1 and my husband suggested me for F2 visa. In this situation I am totally confused. Help me to decide Which visa type I should apply for F1 or F2 in next try??

Please provide reasons as to why your F1 was rejected in the first place on 2 occasions.
