You are experiencing erections which occur when you are sexually aroused. This normal. Many erections seem to happen for no particular reason.All of this is medical talk: "Physical and/or mental stimulation cause nerves in the brain to send chemical messages to nerves in the penis telling the penile blood vessels to relax so that blood can flow freely into the penis. Once in the penis, high pressure traps the blood. This causes the penis to expand and sustain an erection."The average length when erect is about 5.6" erect. If you are smaller, it will grow as you grow. Most males do rub or stimulate the penis. This is also normal.
When erect, a penis can either stand straight up or stick out straight. Everybody's different!
If you stick your penis up inside her and it breaks the hymen, she was a virgin.
