When I am are about to ejaculate my legs go all tingle and my semen is clear I am 14?

dude im 14 and i am having the exact same problem as you. the semen is clear because your still maturing and it hasn't got all the ingredients yet. its completely normal for people at our age so dont worry about that. but you should stop if your legs go all tingly because you will start to get blood in your semen and thats not good so you should stop like i did
