yeah try and avoid that girls don't really like that. Try porn
If you mean the foreskin getting stiff, you need to clean your head more and maybe start gently masturbating If you mean your whole penis getting stiff it is because of the blood rushing to it when you become sexually aroused...
Because all the pressure and the blood goes into you penis when you are seein something sexual.
You stick your erected penis into a girls vagina. If you cant spell "sex" right i am going to assume that i need to explain to you what erected means. It means that it is sticking up and is very stiff.
My penis alright *gigedi gigedi* an erection is when the penis gets stiff, you jerk off, feel good.
the stiff ones are either fake or the girl is very horney. the bouncy ones are good
Girls go not get erections. An erection is when the male penis becomes bigger and stiff. I think you mean "aroused" and there are several things that might happen. Her nippels might get hard, he vagina will get moist...
The strict code of the stiff penis
A boys or mans penis gets stiff (erect) when he gets sexually excited. It can be due to oral stimulation, touching by a partner, masturbation or even upon waking up.
Because girls put stuff in their hair so it'll hold its shape, like gel and mousse.
If it is stiff and longer than 5-1/2 inches from the bone behind the top of your penis to the tip of your penis, then it is above average. Size means very little . . . don't get hung up on size.
