Depends on which one. Some cause warts and sores. Others don't show much.
you can get std's or get herpes if the penis has has a cut on it STD is sexually transmitted disease. You can get gonorrhea, hepatitis, HIV, herpes, genital warts, chlamydia..... To avoid the potential to get any STD, use a condom every time.
No. this is a perfectly harmless pastime and even his ejaculation will not do you any harm.
you might have an STD. you should go see a doctor!
If you have any spots or lesions on your penis or testicles, then you need to get it checked out by a doctor. It may mean that you have contracted an STD which needs to be treated.
i dont have a vagina but yes, you can contract an std if the girl has an std whether its visible or not. So it would be great for the both of you guys to get tested for any sexually transmitted diseases. Condoms work great but celebacy works better.
Yes, if the blood is from a person infected with HIV, and comes in contact with the penis opening or a cut/sore on the surface of the penis. BTW, you can only get HIV, not AIDS. HIV causes AIDS after 8 to 10 years
It's not an STD if that is what you're worried about, and whether it's the condom is hard to say, what I know is that if the penis is stimulated for too long by something dry-hand etc then that can happen- don't worry though, it's not an STD or dangerous in any way.
The same as it always has. You should still be growing and that will probably include the penis, but don't expect any big or sudden change. At 14 you should have been having erections for a while so that shouldn't be any surprise. Size can be anything because everyone is different. Your penis is the size and shape it is supposed to be for you.
No it doesn't make your penis smaller. I had on for 10 year and I don't see any different
actually this sounds like an STD if it smells so bad...
No, they dont look any different.
Any size is normal. Everyone's different.
