NO-women dont have testicles:)
no
12cm
Im a woman so im not 100% sure, but I think some size variation between the two are normal but if its actually double the size, then Id say you need to ask a doctor.
Any change in the size of a testicle should be taken to a doctor. It could be something simple like a swelling from an infection. See Related Links below.
Have sex with a woman. One is enough.
For me, not really, but I don't know about other guys.
they are about the size of a car! lol not true
Go see a Doctor.
One bull testicle (depending on the size and the breed of bull you are referring to) can weigh around 1 to 2 lbs.
They are very large for their size. I would estimate half the size of a human testicle.
"The average testicle size after puberty measures up to around 2 inches long, 0.8 inches in breadth, and 1.2 inches in height." - Wikipedia, http://en.wikipedia.org/wiki/Testicle
For a woman size does not matter...... what does matter is the irrection and timing of sex and women love those men whe can generate great sex before intercourse.
