I have read about many people in their 20s who suffer from sexual problems. I take extreme care of me penis. Will it help?

Iâ€™m an 18-year-old man. I have read about many people in their 20s who suffer from sexual problems. To make sure this does not happen to me, when I get up in the morning, I massage my penis with olive oil. After that, with a high pressure pump I target huge amounts of water on my penis so that it can take a lot of pressure even in difficult situations. I usually donâ€™t masturbate a lot, but when I do, I masturbate thrice so that my penis can take a good amount of pressure. I also dip it in a glass filled with ice so that it can function properly in extreme conditions. Can all these activities help me in future or can they harm me?
