I don't use laxatives, but I have been given stool softeners following back and hip surgery.
In the 1970's I had minor surgery, and those were the days when you still got an enema the night before. It was given by a skilled nurse, and was quite enjoyable.
After surgery when my bowels didn't move I was given a laxative. I wasn't going to be allowed to go home unti I pooped! That was in the morning, and by evening, even though things were gurgling it hadn't worked. During visitors hours another nurse came in and announced I was going to be given another enema. To my surprise a female friend of one of my friends commented she'd like to be there for that! Which got a laugh, and now I regret I didn't follow up on the comment.
Just after visitors hours the nurse comes back with a 1500cc bucket and hose filled with pretty hot soapy water. This is also just about the time I'm getting a pretty good indication I am going to have to go very soon. But pass up an enema, no way.
The nurse has everything prepared and me on my side, and as she inserts the nozzle I get the feeling I have to go right now. Still I want the enema, so I don't say anything.
The nurse opens the clamp, but nothing much happens, it is like an equilibrium, and now the urge is strong. The bucket goes higher, and to,my surprise the water starts to flow pretty good, and the urge subsides. Before you know it, all 1500cc is in.
Now the nurse wants me to hold it, but things are starting to work again. I tell the nurse the laxative had just started to work as she started the enema. She said she thought that might have been the case, but wanted me to try to hold it a little longer. Having held enemas for close to an hour when playing, I'm pretty good at holding, so I managed, but when she finally helped me to the toilet I just exploded.
As she left, she told me not to flush, so she could check the results.
After I finished and she came back and flushed she asked me how I felt. I told her that the soap burned a little bit and it felt like there was more. That was a lie, but she said, well, I think you need another enema. That she had other things to do and would let me rest and come back later.
When she came back she said she was going to do,enemas until clear, which I was certain was going to be only one.
So back into position on in goes 1500cc with ease this time. To my pleasant surprise it is far from clear. And when she checks, it's pretty much like, she's pleased to have to give me another. So here we go again, and I decide, what the hell, I say, "Do you like giving enemas?" Her answer, to my surprise,,"Do you like getting them?" I say yes, and she says, "I thought you did, you never complained, and I do like giving them."
So we finish without saying much more, I go off to the toilet, and I'm thinking dinner is working its way through, because it is still not clear. The nurse checks, and say she will,give me another one, because I am not clear. I say fine, I'll take as many as you want to give me. Her answer, I'll keep giving them to you as long as you want, but if the nursing supervisor checks and your return is clear I'll have to stop.
I say, I understand, this is our little secret. Well the nursing supervisor never checked, and seven enemas later we were still at it, but by that time I was pretty tired and drifted off to,sleep.
I never saw her again, and nothing overtly sexual happened, but it was a night to remember.
