Is there a demand from guys to take on male subs who want to be feminised and turned into sissy slaves/subs?

I mean if you ask does something exist, yes it does. But submissive men are the most common commodity, submissive ladies, then dom guys then Dommes. So it's probably not the details they are hung up on, more like they have a lot of choice overall and limited time, attention and desire.

Good luck though!

Like RBWells says, there will always be more submissive men than there will ever be willing and compatible doms. Combine that with the fact that Feminization/sissy kinks have a tendency to attract people who are internally conflicted, uncomfortable with their sexuality, and prone to both flaking and purging makes it tough to explore in earnest in a legitimate and safe manner until you've fully come to terms with some of these things.

Most legitimate doms can sense these things so most of your interest is going to come from chasers and pro-dommes looking to take advantage of you. Is your only kink that you're looking to explore feminization? Because if that's the case, then a lot of the times your ads will also sound like you're just looking for a kink dispenser relationship, which is a very one-sided and selfish relationship for a dom to be in. Keep in mind that all relationships have a give and take to them.

What I would say from my own perspective is: first and foremost, find a queer and kinky person you love. THEN focus on the feminization etc etc. If they're open minded and cool, they're probably going to be willing to give it a try. It may not look exactly how you picture it, but with the right person who cares?

yep lots of men into that. there are some sites specifically for that very thing. you can find them if you look for them. Not sure I can link here.

Oh, absolutely a demand.

The problem is that it's a very complicated thing, and that means you can't just gonna someone willing, they have to have the experience and skill as well, or it's going to end up bad.

It really isn't something most doms are into as their own kink. Picking up the "tricks if the trade" means having to spend your own time learning something instead of having fun for your own ends, if it isn't also your kink. That's as rare as finding a dom that has the kink tbh.

Back when I participated in the local scene, the feminization side of things was fairly rare, and not part of what most bdsm groups did when they met.

That being said, it can be fun to take part in, even if it isn't your kink. I have done scenes with sissies before, and while it isn't something I would want to do regularly, particularly if it involves sexual intercourse (be it oral or anal), even that is fine for the occasional bit of experimentation to get out of the comfort zone.

That's where most doms I've known stand on it. It's not their main focus because it really is a focus for a sissy. If you aren't doing that part of dominance, they tend to not be fulfilled by a session. It's kind of like pony play in that regard, you have to specialize in it to really get anything out of it long term.

But be patient. Be willing to communicate well with any potential dom so that there's no crossed wires. Doms that aren't used to the feminization genre of play can make mistakes that are easy to avoid if they're talked out in detail ahead of time. The few times I did it, I was lucky enough that the sissies I was playing with were very experienced and let me know what they needed rather than expecting me to magically know the ins and outs of it all. I know that breaks some of the immersion, but until you find a long term partner, that's the only way to go.

It comes down to the demand being much higher than the supply.

It's absolutely a thing but from my personal observation, there are far more subs than doms that are into this. Trends very greatly in different regions though. If you're willing to travel I'm sure you could find someone.
