I have been breeding for about 2 years or maybe 3. I bought a lil guy and have breed him 3 times, well this time when I was going to breed him with my girl he was trying to penetrate but it was not happening so I was going to give him another try before I thought maybe I was off on her dates. She is not too much taller than he is but I did have a pillow for him. He never got inside and his lil thing was hanging out and I had to help him get it back in. SO I am thinking I am too early but would like other opinions on what could have caused him to not be able to get inside. THis is this girls first time breeding.
Thanks
