First time trying progasm jr

Progasm Jr is very smooth and can come out as easily as it goes in. Be careful not to use an excessive amount of lube! Also be sure you are totally relaxed and doing muscle control and you will be pleasantly rewarded! The smooth contoured shape makes very good contact with the prostate and serves to massage as it rocks back and forth. If you continue to have problems, lay on your side and do nothing and see where it leads you!

I'm primarily a Helix user myself (Helix Syn Trident to be specific) that recently got the Progasm Jr. and will admit that it's definitely bigger than I'm used to and can take a bit of adjustment before it's comfortable.  Like you, I didn't trust it to stay in so I wore boxer briefs the first few times I used the PJ but I've since grown more comfortable with the toy, and have had no problems with it slipping out.  In fact once it's in there, it stays and those tabs really bite into me, to the point of being uncomfortable!  And it's definitely bigger around where it seats properly, so my asshole definitely felt like it was being stretched a bit, and took a bit to get used to.  Even now I can tell with my finger whether I am feeling relaxed enough to have a good session with it; still working on it there! 

The only toy I've had shoot out of me was actually the MGX Syn Trident, not because of its design, but because I thought I had it inserted far enough and took my hand off it to relax and let it slide the rest of the way in by itself--it turns out it was intent on sliding the other way! 

You know how with the Helix even after you insert it, sometime the tabs don't contact enough until you've relaxed enough and the Helix actually settles where it's supposed to?  It's kind of the same thing with the Progasm Jr.  Personally I think that your worries over the PJ sliding out will keep you from relaxing properly and allowing it to seat itself where it should.  So wear underwear to bed, put a towel down, make sure you're about to wash your sheets anyway, whatever you need to do, if it will help you relax and get the thoughts of trepidation out of your mind.  Because that will hang up your sessions.  And I think that however incrementally you need to allow yourself to trust that the PJ won't slip out on you will help a lot.  Experiment, be careful, but when you're ready take that leap of faith, and you'll be rewarded.  Good luck! 

Now your thing about ejaculating almost instantly after inserting, that sounds fun!  As long as it's not a regular occurrence.  I just ejaculated with the PJ in yesterday though that was due to a little help from my hands and even then the toy didn't shoot out. 

Yeah now that I think about it, I definitely over did it on the lube. I just thought because it’s a bit bigger, more lube made sense lol. Also when I lay on my side or the stomach, the penis tends to rub on the mattress and gives a form of stimulation that makes me ejaculate so is laying on the back safe with the PJ? I’m still surprised as to how I came with me holding the PJ and as soon as it hit the prostate, BAM!!! I worked out legs earlier that day at the gym and it tends to raise my libido and testosterone levels from working out so perhaps my body just wanted to release and the progasm was what did it!

@faith-manages do you ever experience any sensations to ejaculate the following day after using any aneros massagers? I experience slight ones throughout the day doing regular things. Just get this urge all of a sudden without being erect or anything like that 

@win123 could be what is known as "butt buzz," but I'm not sure without further description.  I definitely can get pleasurable sensations centered in my prostate, do some research on Aless. 

Also contrary to what the other guy wrote I think there's no such thing as too much lube, especially the first few times you use it!  It is bigger and will take a little more getting used to. 

@win123 The pro jr is my goto aneros and I primarily ride on my back.   I agree w/ @faith-manages...there is no such thing as to much lube.  I also get the echoes of pleasure after a really good session...Sometimes I'll just be going about my day and some way I move puts pressure on my prostate and I get a p-wave.  I also experience it when I urinate sometimes.  The sudden waves of pleasure can be an unexpected but pleasant surprise.

I felt it slowly touching my prostate gland and I ejaculated immediately. No stimulation of any kind.

Well, I'm sold. Where do I sign lol? 

That is awesome. How long have you been using the helix? 

@win123

yes . But usually because I’m thinking about my last Aneros session. I will contract my muscles as they are pretty much well trained. I enjoy the moment, then focus on something else. Yes, I have masturbated, at work, when these sensations can get intense.
