The other day, I tried to masturbate with a small object shaped like a penis but it is far far smaller than a penis let's say maybe twice smaller. I had some problems inserting it. I felt like I was tight and it hurt when I insert it or took it out. Is that normal for a virgin ? And there were like a sensation of fullness in my vagina and it didn't really feel great. And will using dildos which are obviously larger than what I use hurt ?
