That depends
Are you male, or female?
(LOL!!!)
Ask her if she likes it, lol. Or try to laugh it off
yes
Check for any sign of an erection.
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.
Yes You should tell her ASAP. Espesially If the ten year old is making inquiries about erections, you see her incourageing other kids to get an erection, or you noticed that other kids are getting erections when looking at her even if she isn't trying to incourage them.
Hormones
maybe she is just trying to be nice and not hurt your feelings,obviously she is not the girl for you.good luck the right girl is out there for you.
Pick the girl who is more you and respects you and your dreams and if u have children see how well they work with each other.If not pick ON PERSONALITY NOT LOOK
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.
"I think you're cute"
i'm a girl so this is pretty simple.first you have to be really sweet as possible.next you have toplay with her flirt,and offer to walk her home.possibly even by her things .then she should see it's pretty obvious that you like her.then tell her nice and smooth she should be okay with it because of all the nice things youdid for her.
That means she likes you or hates you! read the card and see, is the words nice or bad? If nice she likes you.
