can it be because I'm using a too small toy?

It should within 10-15 minutes, feel smooth sliding, warm and pleasant. Maybe even up to 30-40 mins to get this result, it depends on the individual I think. If not, maybe wrong size/shape for you, or maybe you're too new and need to give it more time to rewire. Also, if you aren't horny/aroused, you usually won't get get nice pleasant feelings which are the start of good things.

@wooripsp Let me ask you some obvious questions: What toy(s) are you using? What lube(s) are you using on your toy(s)? Are your lube(s) compatible with your sessions' toy? Are you using enough lube? @handsfree59 is correct; you should be sufficiently aroused before the start of a session.

IMHO, the size of the toy is not that relevant. I have some small ones (HIH 950, SGX) and still find them to be very stimulating on my prostate!

I have the Eupho Trident wich is a thin device and I also have the Progasm wich is the largest massager you can buy from Aneros.
Both devices are working fine for me. So I think the size does not matter that much.
For me it sounds like that you have to practice a bit more on relaxing and rewiring or maybe your toy really do not work for you.
If I was in your situation I would give an Aneros model a chance. Exept a little money you have nothing to lose.

Have a great day,
Ed.

IMHO I would agree with the other responses. I also bought an Aneros clone to start with 3 1/2 " long. Then I bought a Helix classic, and then an Eupho Trident. After trying all three I usually use the ET which, is the smallest one. I think it is not so much the toy but your mindset going into it.
Don't set a goal just enjoy the session and try to encourage the good feelings. I have discovered how sensitive my nipples are and how they are connected to my prostate. Just enjoy the session and remember there is always tomorrow.
Enjoy the journey

Get an Aneros device, not a knock off.
Next let's make sure you are doing everything possible in prepping - if you like you can try my pre-fligh check list:

- Clear your schedule, have NO distractions and NO concerns**
- make sure you are well rested
- Charge your phone (prep a playlist)
- eat food (a little)
- Evacuate bowels 1 hr before
- Have a hot shower and a hot beverage (if it relaxes you) or a little water (a little)
- Sanitize device
- Be aroused / relaxed, que up playlist
- Pee, stretch
- Apply Lube (5-6 ml fluid)
- insert
- lay on side both legs bent (top leg more than lower (I like a body pillow for this or my wife)

- have no expectations.
- Slowly breath in and out deeply for 2-3 minutes
- Continue rhythmic breathing and add a constant 25% Pelvic (stop pee) contraction
keep holding the contraction (an easy gentle held contraction - if you can't do that try less intense*
- contract your anus muscle (stop fart) - maybe to the beat of the music (try to hold the other contraction - if not just alter them)
- if you need to pause and relax a bit - by all means RELAX
- listen (Mentalky search) for any twitch or sensation in your lower abdomen) if you find one mentally FOCUS on it - basically try to "feel" it more... tell your body to add to it and build on it, but don't physically try to add to it or build on it (until you can master finding it) - you might "squash it" if you physically try to enhance it

let us us know how that goes for you. Good luck!

* control over your Kegles are key for me... so you may want to begin doing daily Kegle exercises if you can't hold a contraction or if it takes a lot of effort to do so.

** by no distractions and concerns I mean none! You don't want the "fear of being caught" or "frustration that nothing is working" or anything like that getting in the way. For example, my wife knows all about this so that I can do what I need to do when I need to do it.

@wooripsp , also I should say, even though that is my full, "pre flight" check list, I don't always do everything on the list... but if I have a less than stellar session it is sometimes due to me taking a shortcut. Also because I've had success, I don't stress when I don't have success.

since you are struggling I recommend you try hitting as many of the items as you can to give yourself the best chance of success. You still may not have success, after all this is my list and what works for me... I'm just sharing to try and help a fellow brother out.

try to keep a list of the things that work for you and don't work for you and begin to build your own "pre-flight" check list.

@HereByAccident I wanted to complement you on your checklist for using the Aneros. It was very detailed and articulate. I can definitely benefit from writing down what works and what does not. Hopefully it will help me achieve the Big O.
Thanks again.

Glad to be of assistance!

Abdominal breathing has given many of my sessions a big kickstart. Breathing in and watching your abdomen expand and exhale making your belly flatten. Gets things going for me.

As mentioned several times above, the smallest toys can provide the greatest pleasure! Aless sessions can be good warmups as well and can get you aroused and primed! Early in the morning can be a good time to pursue activity as you are totally relaxed. My favorite toys are small - Peridise Tempo EuphoTrident and have given me fantastic results! Excellent checklist above is a good reference but pick what works
for you. And relax relax relax and enjoy enjoy enjoy!
