Jelly Jammers Butt Plug Help

Hi There, my partner and I are new to anal play and decided to purchase a set of 3 butt plugs, the set was called "Jelly Jammers" which included

largest is 160mm x 45mm

Medium is 130mm x 30mm

small is 110mm x 25mm

The smallest went in with no resistance, the medium was also easy, the largest took about 15 mins of slow, gentle, well lubed working in but we got there.

My question is..... is it normal to have a dull ache for a day or two after using butt plugs? we used plenty of lube and didnt force anything.

Yeah its just sore maybe take it a bit slower next time . When you get used to it you can relax you're muscles easier.

So it will be soreness and not muscle ache from the stretching then?

Can you run a "marathon" without having running an half mile ? and without to be sore the next day ?

Just reporting in on my second attempt, oh my god much better, lots of lube and working in gently, found out that if I pull it out about one inch I can then suck it back in, lovely feeling

i did this lots of times and the muscles relaxed nicely, its strange as it makes me feel both horny and also relaxed!

im still wearing it now as I dont really want to take it out 😃
