A few mentions were made us using a Fleet when doing a first enema with a GF or BF. Why? Anyone who doesn't purchase a bulb syringe or hot water bag with a variety of attachments is eliminating the potential for enjoyment before the game begins. Maybe even long before your potential partner agrees to the enema experience. You want to make an enema an enjoyable experience, don't you? When he/she says "yes, let's try it", then you do things to give your partner an opportunity to back out (no pun intended), well, that's like saying "hey let's play ball, but first I've got to get a ball, bat and glove."
Okay, you've talked it over with your partner and the game is about to begin ... getting the partner relieved of clothing is the first goal ... that gets the juices going, so to speak.
Then let the potential recipient see you prepare the solution, whether it's filling a bag with clear, warm water, or filling a bowl with a solution so you can use your bulb syringe.
Guy, I'm going to tell you what I love best ... my hubby loves to have me lay across his lap, and I love this position, and he very slowly, very gently, lubes all necessary areas and the nozzle. He makes sure his finger penetrates me so some lubricant is on the inside of the channel. Then he takes the filled syringe, gently inserts it into me, to the tilt, so the speak, gently squeezed it so that I can feel the water entering ... but not too fast. While he's doing this, maybe on the second or third insertion, he's also massaging other important areas of my body ... I usually get totally aroused.
Now, with your partner ... be very gentle ... the first time is so important ... done right, your partner will look forward to future experiences ... hopefully on a very regular basis.
And remember, the e-session is only the start. A shower after is so important (remember, the recipient may need extra time to purge him/her self), followed by a nice toweling off session and then, finally, well, if I've got to tell you, there's not hope for you, is there?
