no, chances are tha while passing throug the clothe all of the sperm died or depending on your boyfriend. if you are trying to get pregnant and your boyriend smokes grass he has to stop for a while to be fertile again. (weed messes up guy's balls)
Chances are, no, but anytime there is any contact with a guy's fluids, there is always a chance of pregnancy, even during your period. The chances are very rare, but can occur.
No, you can't. Unless he was inside of you or came on your vagina with no pants on, you're not going to get pregnant.
The chances are zero , as the sperm cant enter your vagina through clothes.
If its penetration and the man was not wearing a condom, or the woman wearing a diaphragm then the chances are very slim. Pre-cum still carries active sperm, but a very low amount. The chances are very very slim, but I can't say its impossible. Best bet to still have sex and be safe is to use protection. Condoms, diaphragms and spermicide.
You can get pregnant if his sperm manages to get inside your vagina. Obviously he couldn't penetrate you if he is wearing his pants, but if he ejaculated his sperm could get through the material and into you. Make sure you take a pregnancy test and don't do this again unless you want to be pregnant.
no
there really wasn't much information for an answers. but here we are: if he ejaculated inside there is a chance, if he was wearing a condom and ejaculated there is a small chance, if he didn't ejaculate there is basically no chance.
Highly unlikely. Not wearing one could increase your chances of injury in an accident.
No-unrelated.
If you are using protection (ie. condom) then pregnancy is unlikely to occur. However, no protection is 100% effective so if you miss your period you should take a pregnancy test
yes if he take them off
No.
