Never force anything into your rectum. Open hose clamp and allow a small amount of water to enter your lower colon. Wait . . . Allow your rectum and lower colon to adjust to this water before adding more. You can massage in the reverse direction to promote elimination.
Many people get better results by repeating the above procedure two or more times.
The most important thing is to be patient and pleased with yourself. Like everything in life, it gets easier with practice.
