Paul writes:
27Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord. 28But a man must examine himself, and in so doing he is to eat of the bread and drink of the cup.
Notice Paul does not say eat the flesh or drink the blood.
This may be of some help to you.

| 26While they were eating, Jesus took some bread, and after a blessing, He broke it and gave it to the disciples, and said, “Take, eat; this is My body.” 27And when He had taken a cup and given thanks, He gave it to them, saying, “Drink from it, all of you; 28for this is My blood of the covenant, which is poured out for many for forgiveness of sins. 29“But I say to you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in My Father’s kingdom.” | 22While they were eating, He took some bread, and after a blessing He broke it, and gave it to them, and said, “Take it; this is My body.” 23And when He had taken a cup and given thanks, He gave it to them, and they all drank from it.24And He said to them, “This is My blood of the covenant, which is poured out for many. 25“Truly I say to you, I will never again drink of the fruit of the vine until that day when I drink it new in the kingdom of God.”. | 14When the hour had come, He reclined at the table, and the apostles with Him. 15And He said to them, “I have earnestly desired to eat this Passover with you before I suffer; 16for I say to you, I shall never again eat it until it is fulfilled in the kingdom of God.” 17And when He had taken a cup and given thanks, He said, “Take this and share it among yourselves; 18for I say to you, I will not drink of the fruit of the vine from now on until the kingdom of God comes.”19And when He had taken some bread and given thanks, He broke it and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.” 20And in the same way He took the cup after they had eaten, saying, “This cup which is poured out for you is the new covenant in My blood. |
21When Jesus had said this, He became troubled in spirit, and testified and said, “Truly, truly, I say to you, that one of you will betray Me.” 22The disciples began looking at one another, at a loss to know of which one He was speaking.23There was reclining on Jesus’ bosom one of His disciples, whom Jesus loved. 24So Simon Peter gestured to him, and said to him, “Tell us who it is of whom He is speaking.” 25He, leaning back thus on Jesus’ bosom, said to Him, “Lord, who is it?” 26Jesus then answered, “That is the one for whom I shall dip the morsel and give it to him.” So when He had dipped the morsel, He took and gave it to Judas, the son of Simon Iscariot. | 23For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” 26For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes. |

No. He says you should not eat or drink 'unworthily' That is, not believing the bread has become His body
