Teenage boys get erections all the time, even when there's nobody around. So if they see someone they like, the erection is likely to pop its head up. Don't worry too much. After a few years it will be much slower to react.
Yes
yes
Ask her if she likes it, lol. Or try to laugh it off
That depends Are you male, or female? (LOL!!!)
Of course, the meet attraction of a girl and contact is enough to enduce an erection
See the pretty girl in that mirror there? ...What mirror? Where? Who could that attractive girl be?
Eat ice cream. It's scientifically proved to keep your erection down. I have the same problem with my girlfriend. It really helped. --- Why would you not want an erection around her? It feels good and if she likes it you might find even more pleasurable things to do together.
They are fun to play with
Hug her while you have an erection. Surprise!..
No. Some people are pretty. We can all see this, even if we are not sexually attracted to them.
no
She should put it in her mouth.
