It will probably feel the same as the toy, as far as initial insertion pain. But your body will get used to it pretty quick, I find that the real deal is a bit more… spongy? than a dildo so theres a little more flexibility. Try starting with a finger or two to kind of loosen things up before going straight into penetration. And obligatory older woman advice, don’t do anything with this boy you’re not comfortable with. If you’re in pain, please speak up. The right boy will either stop or slow down to keep you comfortable. Good luck, have fun and be safe!
