If you are just getting started in developing as a male aside from the fact that you have a huge amount of hormonal activity spurring you on the newness of the emotion you are undergoing make you want to keep experiencing the feeling.
all the time as they are always sexually aroused.
All men and women when sexually arroused is because of testosterone, than any other hormone.
No
Everyone is different. When you are young your nipples may be hard a lot of the time. As you get older your nipples tend to become hard only when you are cold, wet or sexually aroused.
No. There is a lot of variance in the amount from nothing to a steady stream. Each time a man get aroused it can vary depending on how aroused he is.
it all depends on what you want from the guy. if you are ready to go all the way or not. just tell him if you are or not. if you don't want sex from him then say no.
all women just wanna have it that's the reason for have sex in lingerie
Of course they shouldn't, because they aren't sexually mature and wouldn't know what they are doing.
Pandas reproduce sexually, like all other animals.
If you get erections then you must be aroused. You may not be thinking about sex, but your body is. For some men, usually younger ones, it doesn't take much to get erect.
If you've got obsessions or spirutal problems; it is possible. I think that person who become sexually aroused when he saw a girl who is crying have to see an alienist ;) That answer is stupid... I think the real problem is that you're human. A crying female is related instantly to vulnerability. When an "animal" senses vulnerability, it will immediately want to strike. In this case the vulnerability is her vagina and you are wanting to strike with your man sword. You're normal for getting boners when girls cry. We all do.
It all depends on the type of girl. Some may like foreplay, which can help them get sexually aroused, and others may not. You should start foreplay slowly and if she has concerns or wants you to stop it is highly recommended that you do so.
