Is there a problem with my clit?

Sooo, these couple days i've been masturbating with no sex toys and i found that it's not like before i get tired even before i finish off and i noticed that my clit isn't really sensitive the way it was before although, i don't usually masturbate alot (probably 2 times a week?) Idk to be honest this is starting to stress me out i'd feel that im horny but once i start it takes forever! Lemme know what you think of this ladies is it just a phase or should i really be worried ?
