Personal speaking: There are no harm done by inserting sex toys, such as vibraters, vibrating penis, and sex toys which were designed for sexaual pleasure. I use them on my woman all the time, but please don't use things such as: cucombers, bannas, or other objects that were not designed for sexual purposes! They may cause infection Just my though!!!!

yep they are safe.

My wife just gave birth to our first 5 weeks ago and obviously I want to have sex again but she is just really scarred to have a sex because of how much it will hurt. Though, she does have a vibrator and I was wondering if she starting using that a few times will that help get her ready and/or help with when we do have sex that maybe it won't hurt as much. Kinda as preperation and training for the real thing. I know it sounds goofy but I just want to make my self clear on what I'm saying.

It isn't going to hurt her to have sex after having a child providing you waited the alloted amount of time the doctor said for her to heal. She might feel a bit larger down there than before, but that will go back to normal in time too, so tell her not to worry.. if you got the go ahead from the doctor, it's not going to be painful, and you don't need a toy.
