13 based on many things. 1) your first question 2) you use no1 instead of no one (so do i tho im 16), 3) the fact that u used kyle as your avatar name, 4) you don't capitilize i (same), and 5) no1 over 25 would ask this question. u asked y do ppl like sex so much so ur obviously too young to ever have had it, so you're probably younger than 18, and yeah just your typing in general. im going with 13, and if not that 14
