Re: is this normal?
Oh yeah! This happens to almost EVERYONE. It usually happens when ur really horny (so horny that you start to precum before you bet an erection) and an erection is soon to follow. It can also happen when you are only slightly aroused, but stay aroused for a really long time (u precum instead of becoming erect). The only other time I can see this happening is when u r really turned on (like on a first date with a total knockout) and you feel really embarrased that she will see your erection, so your body precums instead! This has happened to me before.
Hope this helped!
