>>1351136While you most likely are correct, some people do start late. I didn't start until I was almost 18, when my significant other of two years broke up with me. I lost my virginity to him when I was about 15...so I guess I never really had the desire since I had someone then. Or something. I'm 21 at the moment.
TL;DR Some people just start late. Though, in this case you're probably right.
Picture unrelated. I have to use a shower head to have my pleasure, so I can't use pictures.
