I agree, and lesbian sex is catching on among younger women, but encouragement would help, and i think the men in their lives could give them needed assurance.
It's normal for girls to be very sexually intimate with each, that's why it's so nice to watch. It brings joy to the heart to see them lick and kiss each other all over and bring pleasure to the body and soul with beautiful orgasms. Girls should be encouraged to be naked with each other as often as possible.
