Q If the left testicle moves up almost beside the penis and virtually out of the scrotum during sex is this normal?
The testicles goes upwards during sex, normally. In rare cases, it may extend to the penis. But, one must avoid it by pulling them downwards either by themselves or with the help of partner. Because, during the thrusting the penis inside the vagina, they may get injured and lead to further complications. If it a recurrent condition and causing some discomfort to you, must consult a urologist for proper guidance.
