A while ago, while I was still interested in using sounding rods, I searched some porn sites for male and female sounding and I came across a couple of videos of men inserting their penises into the women’s stretched urethra rather than their vaginas and orgasming into their bladders.
There are some fairly extreme kinksters on this forum so has anyone ever tried this?
I would have thought that it would be a perfect way to end up with some severe UTIs.
Oh no - very no … just don’t do it …
To quote that rich business Den tv show
“I’m out”
I’ve seen what you are talking about but never know someone into it.
How bored with normal sex must you be, to end up at the end of the path where your thrusting your cock into a woman’s Urethra?
Get some help 
That’s plumbing a new low!
Agreed, seems a surefire way to an infection, can only be for porn audiences, can’t see this being a regular thing
No I already have perfectly good holes thank you
Nice one!
Eeek just the sounds of it makes me think it would maybe sting a little 
I knew of a couple trying to conceive for years and ended up having IVF to get a child of their own.
They were in fact having urethral sex and had never had PIV and both each others first and only sexual partner.
That is something new I’ve not heard before.
If that is not an indication of how sex education is failing, I don’t know what is. Yikes.
Before reading the other comments, my initial reaction was, “Ouch!” … During and after.
Glad others seem to agree 
I can’t fathom how a normal sized cock would slip easily into a urethra! 
Practice
Actually, I’ve thought about it! I seen online that it was a possibility, and personally I like the thought of having yet another opening I can use.
But… I think few people would be able to stretch far enough to do it. I’ve discovered that while I really enjoy having a partner’s finger inside my urethra (it feels amazing!) I think stretching any farther is not going to happen. It ain’t made for that, after all.
And yeah, UTI. I’ve had a couple already with what I’m doing, mostly because I really like having the opening licked. But having a penis in there would probably mean yet another course of antibiotics.
I’m with you on that. The first time I got a UTI after sex I just found it odd, then it happened again, and again. Now I realise it’s because I l-l-love some U-spot stimulation - like, maybe even more than clitoral stimulation (or maybe not?). Now I just kind of accept it for what it is, have cystitis drinks on standby, practice good hygiene and drink (and pee) plenty after sex. It is what it is, I’m not giving up my orgasms for a chance to pee less often.
As for urethral sex? Just no, especially not ejaculating into it. I used to know someone who had to have dialysis four times a week. Intentionally putting things that shouldn’t be into your urinary tract seems like a surefire way to be joining them.
I am not overly endowed and can not imagine it would be easy or fun for either partner . Seems to be a potential extreme damage act , no thank you .
Wow
Everything is kinky for someone, but this one isn’t one I’d want to try.
