I was one of those little girls. I never was comfortable when they changed the way they gave communion.
It is most proper to receive the Eucharist on your tongue. Don’t worry about the priest touching the tongue — most priests know that the host will stick to your tongue and they avoid that touching.
As for the Holy Blood of Christ in the chalice if you receive under both species; any proper Extraordinary Minister of Holy Communion knows to slide the purificator down through their fingers thus using a different surface to cleanse the edge of the cup. Then they should turn it a quarter of a turn before offering it to a new person.
If you get to the end of the purificator, pause and refold it and start using an untouched surface of the purificator and again remembering to turn the cup 1/4 turn.
