How to be more OPEN

I never had vaginal orgasm just by clit stimulation “by myself “! I being with my partner for 5 months and i dont know im TO SHY to tell him if i can rub my clit while he’s penetrating me because that way i can orgasm, everytime i try to touch my clit he gets my hand away and i want to tell him that will help me more but im shy, when hes giving me head i never cum or when im about to he moves like my clit its so sensitive and i love to get it licked but its the part that he less touches???? And im shy to be dirty and tell him to lick my clit more then anything!!

Any tips??
