i need help with my sex toy!!!

okay so i just bought my first sex toy! it’s a purple 8inch dick. i can only get the head in me, for some reason i can’t get farther than 2 inches, i used lube too so i don’t understand why i can’t get the toy in me all the way.

if it helps i am i virgin, i have never mastered bated before and i have never put anything up in me before. never used a tampon

i am going to try to use a tampon when my next period comes
