We have been pegging a few years now and the dildos we enjoy are getting wider but my husband still loves depth and we have started playing with 10 inch which I consider eye watering
I cannot imagine it’s going to get much deeper but we do own a 17 inch snake (creature cocks) but have not used that as yet
So what’s your length
Have only been pegging for a year and not too often maybe once a month. We use a 8 inch dildo and can’t take it all but not too girthy did try a 10 inch but couldn’t take it
It depends how relaxed I am I think. I can take depth easily sometimes but not others. I’d say 10 inch was about my max, it’s great fun trying.
We’ve just started on our little trip down the rabbit hole over the last 2 months after Mrs Caged decided she liked the idea, and her imagination knows no bounds progressing from a small 5” now reaching a eye watering 13” girthy monster, only matched by the glint in her eye
Longest I’ve had was 12” but took a lot of working up to it 
10" long x 9" circumference.
Also the Doc Johnson Titan Intimidator. 10" x 10".
Look up digestive tract diagram. The colon meets with the large intestines and it bends 90 degrees. If youre putting in big toys that reach the intestine bend youre just battering your intestines.
Longest I’ve taken is a 8 inch but I prefer girth to length generally.
8 1/2 inches regularly. Looking to go a little deeper.
Welcome @Caged-owned
Afternoon, evening, CandB
@Caged-owned firstly welcome to the forum and secondly 13 inch …. And I ask if you can take that to its full length
We are working slowly and I enjoy using and buying dildos as well as the harness - but we have taken 2 years
Hi batjamboree, little background in my distant youth I did play around shall we say so knew the pleasure anal could bring to the party, and forward fast to now when Mrs-Caged raised the idea, I was well aware of the pleasure/pain when starting out , luckily she’s lovely and patient or was until she realised she had a Dom streak, so Mr big as we call him was brought out more and more until she finally had it all the way in Fri just gone, roughly 3 weeks after purchase. The actual size is 13” but 11” usable and 3.1” width,we did measure after she read someone else’s forum post and the actual girth is 9”
Max length many years ago when my wife was pegging me is the same max length I " self peg " , 9" . I have to be in an extra slutty mood and warm up before using my 9" , it is also 6" around . I think part of the slight discomfort is the life like cock veins are a bit harder . As a former emergency medical tech. , I am cautious when testing my limits . Same with sounding .
9 inch is certainly impressive- when we peg with the longer dildos I don’t thrust I just slowly insert but I know when to stop ..
I have always been interested in sounding and would love to try it - but my husband is not interested- but he is amazing sexually- I adore his crossdressing and spanking and I adore pegging him
I tried sounding multiple times , wife did not want to see or participate in it however . Not really my cup of tea . Not to mention chance of injury .
Average cock size is fine. Every now and then I want to be stretched or to have a bit more depth, but mostly just want a good standard size
@Trixie-n-Russell my husband is the same - most of the time we play with modest size dildos which I can slip inside and thrust - but we do sometimes change the dildo for a wider or longer during play
The best Sexterminatrix and I have done is me sitting on 8 inches with 6.25” girth which is a struggle unless I’ve stretched beforehand. Intimately I would like her to use it in a harness, but I think that would be the limit for us. Anything longer and you’d risk serious internal injury unless you were extra gentle … which can lapse in the heat of the moment. In addition to this, most of the pleasure receptors are located an inch or two from the anal entrance, so I can’t really understand what the extra depth would provide, pleasure-wise..?
I am at 14 inch but that only occasionally
