Is it normal to stop loving women and start wanting a man

well i'm 21 and i love girls but every day feels like i'm not into girls any more and i start looking at men like i do Skittles ... so beautify with there six pack or some make me feel loved

as for women some girls love me cause im sensitive sweet and kind
but i just don't look at them like i do skittles although some days i do

its like 1 day i like men and 1 day i like girls and someday i feel lost like i don't know what to do although women jeans omc so comfortable
