Answer:
Make sure you are arroused and lubricated. Don't buy one that is too big. Lie on your back and slide it in your vaginia like it is a tampon.
And no, you can't get pregnant.
ummm
can't get pregnant... it can't ejaculate, it's plastic
and you just put it in, like a tampon, carefully
Unless you put some active sperm on the dildo no you arent going to get pregnant by it. Second, slide it in till you meet resistence then back off. The resistence is your hymen, which is what makes you a virgin
