No, you can not get pregnant through your jeans.
yes why not
trousers are basically your underwear and jeans are your pants
Yes as long as your parts don't suck the in fly's of your jeans
socks underwear shoes t shirts jeans
No. The sperm needs to be in contact with her vagina, unless she was wearing your underwear she is not pregnant.
Some discharge is normal, however if it is extensive amount you should consult a doctor.
I would suggest briefs, bikini briefs, jockstrap, thong, or ever maybe
The type of underwear that a 13-year old boy should wear with skinny jeans is a thong because it won't show up.
