>> “Jesus said, “This IS my Body.” Similarly “This IS my Blood.”
I believe Jesus’ words and don’t question them at all.” <<

So then you hold that he drank his own blood, and ate his own body?

It seems that you do not understand transubstantiation, do you?
trans = transfer
substantiation = substance
The wine is transferred into the Blood of Christ, but still appears as wine.
The host is transferred into the Body of Christ, but still appears as unleavened bread.
So Jesus drank wine as did the apostles, and Jesus ate the bread as did the apostles.
Hope this helps.
When we receive Communion we believe that we are receiving the transferred substance of Blood and Body under the appearances of wine and bread.
