nope. thats gross.
At 13, you like to explore your sexual feelings, it's normal to try things. Don't do anything that makes you afraid or makes you feel weird.Talk to someone you trust. Maybe an open minded older friend. There are many types of people in the world,and we are all worthwhile.
Whoa a minute kid! ... Let me translate... (Don't they teach you English were you live?)
I'm going to write for you the question you asked - but this time, in English:
"Would you sneak into your friend's house, and raid her pantie drawer, while she's asleep, like I did, and try on her clothes?"
Aside from that.. perhaps you're a 'budding' Tranny or Drag Queen?
No handling someone else's underwear that may have streak marks on them is not on my top 10 things to do, perhaps should get some professional help ...
