I have only had short conversations in a few stores myself - supportive ones in places like health foods stores where enemas aren't all that strange. But hubby really hit the all-time drugstore conversations jackpot once.
This was years ago, before we were married. He then had a love-hate-fetish thing about enemas and suppositories. Hearing about them or thinking about them could be very arousing for him, but getting him to actually take anything was something else - and he very frequently needed some help there, especially when he traveled. In drugstores hubby would pay attention to anything interesting going on in the enemas aisle, but he was much too embarrassed to start a conversation about them.
Well, then-future-hubby was off on a trip to several small towns for his work. I had reminded him to pack the glycerin suppositories I got for him and to use them if he didn't poop for more than a day or so. Of course, he didn't even pack them. I made him promise that he'd go get some as soon as he got off the phone to me and actually use one; he had admitted that he was definitely well overdue. The town pharmacy was already closed so he went to an independent brand discount store or general store that was still open. It wasn't busy and had several clerks standing around - and it had a well-equipped health and beauty aids department; it even had a shelf space for suppositories, along with some disposable Fleet enemas and a generic or store branded kind.
An attractive young lady sales clerk came by to assist him. She said the suppositories were on a big sale and had sold out, but she thought they had just got another bunch of them in. She motioned for a clerk in the next aisle to come over, and two clerks joined the first - another attractive young woman and one who was a motherly type - all very friendly and apparently in no rush. Then-future-hubby would have preferred to duck out about then, but the clerk was friendly and direct to him and even somewhat insistent, telling him to just stay put for a moment - he wasn't going to get away without something to help him out. He was just thankful that the clerk didn't yell out, 'A guy in aisle three needs suppositories!'
After looking about while chatting with him, the three clerks decided that the store actually had gotten more suppositories in that afternoon but they hadn't been put out on the shelves yet; they would still be locked in the receiving area and the clerks wouldn't be able to get to them till morning. The first clerk asked if he could wait till the next day or was he really uncomfortable. He explained that he was on travel and that he had just promised me that he would take care of his problem very promptly. They all seemed impressed that he was trying to keep his promise and take care of his bowel hygiene. The second clerk suggested the Fleet enema and asked him if he knew how to use it. (No, of course not - he had no idea! Explain it slowly...)
Then the three women started a discussion that then-future-hubby says seemed endless, like it was the first time they had gotten to talk about enemas and suppositories. The three of them gave him advice while also discussing among themselves their own different preferences, which types caused the worst cramps or might lead to accidents, the best ways to do big enemas, how much trouble they had getting their kids to takes these, how much more trouble they had trying to get their husbands to take anything - and how they could always tell when their husbands or kids needed something. One had apparently worked at a nursing home and had quite a bunch of suggestions. And they went on and on. Each one pretty much had a somewhat different and fairly detailed suggestion for him.
At first, then-future-hubby thought he had hit the enema-eavesdropping jackpot. Eventually he got worried that he was going to lose it and come in his pants listening to them. He finally thanked them, bought the Fleet enema, and - wonders! - actually gave it to himself that night (or at least told me that he did).
When the first clerk was checking him out with the enema unit she told him that she hoped that all their talk hadn't embarrassed him and that she knew how embarrassed most guys seemed to get about enemas and suppositories, and that she thought he was quite a guy for keeping his promise to me. She explained what she thought would be the easiest way for him to take it. And she told him that she was going to put aside a jar of suppositories because with their sale they were going quickly, and that she hoped he would come in to buy it on the next day so he would be able to keep his promise to me and to keep his bowels happy. Then-future-hubby had to finally hurry out of the store for some quality time alone in his car.
He came back in on the next evening and bought the jar of suppositories from the same clerk. She talked to him one-on-one for a few minutes, asking if the enema was okay or too awful, giving him more advice about bottoms and warnings about bowel cancer, and asking his advice for how to make her own husband more accepting of enemas or suppositories. Then-future-hubby was taking off on the next day for the next town on his list, so the clerk got him to agree that he would really do what he had told me he would - to put in a suppository every morning if he hadn't had a BM the day before. And for that trip, at least, he actually did. (Or told me that he did.)
Beyond being arousing, it really helped him to hear the three women talking about enemas and suppositories so matter-of-factly and generally positively. Of course, things changed quite a bit once we got married, and I made it all very positive for him.
