When I was being trained for my First Communion when I was a kid, they taught us how to receive it in the hand so I never really got proper catechesis about how to receive on the tongue.
How can I position myself to ensure it's secure? When I receive, the priests seem to take a little longer to place it in my mouth (I'm guessing because they are so accustomed to placing it on people's hands so they don't get enough practise). At times the priest would accidentally touch my lips which I'm sure isn't pleasant for either him or me.
Should I stick my tongue out? I've seen and read of people doing that but if a priest might accidentally touch my lips when I don't stick my tongue out, he might very well touch my tongue if I do stick it out. Even more would that be unpleasant for us both, and really bad hygiene.
Should I sort of lower my body so I can tilt my head up? Would that make it easier for the priest to securely place it in my mouth?
Also what should I do with my hands? I can't fold them in front of me because the priest would think I'm intending on receiving the Host in my hands. But if I place my hands at my side and sort of stand at attention, I feel a little bit like I'm being irreverent (I wouldn't pray in that position, much less should I be receiving the Eucharist that way).
