Hi Riley, I will be more than happy to share my Catholic view point on the Holy Eucharist at mass and showing love for Jesus.
Many of us stay after wards, to continue to worship Jesus, and there are many in the pews and at the altar rails-all of us kneeling down.
Some are saying the rosary, some are saying divine mercy, some are just on their knees head bowed and hands clasped, doing a deep praying devotion of their choosing.
Some go up to the altar rail to kneel down before the cross and tabernacle, others go to the Marian shrine and pray there on bended knee.
Still others walk from station to station, silently praying the stations of the cross.
Others quietly read a prayer book or other spiritual reading in their pews.
What ever deep love and devotion that you want to give to Jesus, you can give both during mass and then in the after mass quiet prayer time.
Riley, there is just something about being down on ones knees that can make a big difference as well, when it comes to showing love to our Savior.
I recommend preparing to partake in the Holy Eucharist by spending quality time at home with the Lord, through deep prayer, especially lectio divino, and listening to His voice.
By developing a very close relationship with Him through prayer at home, the going to receive Him at mass brings such sweet joy and peace.
Another strategy for me is to pray the Anime Christi prayer after communion, but to quiet sing it in my heart as I learned how to do that by worshiping at home with this prayer, on a video I liked.
Its not scrupulous to be so in love with the Lord, that the 10 minutes of going up and coming back would seem as not enough, and you have so much in your heart to give Him.
Can you stay afterwards?
I tend to be scrupulous.
