People use enemas for a number of reasons including:
* Many people gravitate toward using an enema to relieve constipation because they received the treatement as a youth and were very satisfied with it.
* An enema provides a pleasing amount of anal stimulation for many users.
* Many women prefer an enema before anal sex to cleanse the area and to free them from worrying about their personal hygiene.
You have a few choices as far as positions are concerned. There are some good candidates.
- The Left Side Position: Lie on your left side. Bend your right leg (upper leg) toward your chest. Keep your left leg straight. This position should be fairly comfortable while giving good access to your anus.
- Doggie style (knee chest) position: Get on your elbows and knees with your head down and you buttocks high in the air. You might even want to put your chest to the floor. This position should give your partner good access to your anus. This position may be familiar to anyone with experience in anal sex.
- On your back: Lie on your back with your knees bent. Your knees should be together while your feet are separate. This should result in you sitting a little bit knobby kneed. This should allow good access to your anus from below.
- Over The Knee: Some people like to receive an enema in an over the knee position. Lie across your partner's lap. This position might put too much pressure on your stomach so you might want to put your stomach between your partner's legs.
