Jared it's only our second time using it we just got it. First time we used it wife was sore for 3 days. this time she isnt sore. I eat her and get her very wey=t, then I fuck her for a bit, then we use the dildo. We use a lot of lube. The head is the hardest for her to get in but once its in i just keep a bit of pressure on it pushing in and as she adjust it goes in more then when its in a good 7 or so inches i start to go in and out very slow till she gets use to it. The key is to fuck her first before using the dildo and it helps that I am 9x6.5 to i guess being a close size to the dildo just take your time and use lots of lube and enjoy.
