If you are actually a virgin still, I honestly don't find it a bad thing. Just be sure, if you ARE going to hold onto it for this long, just make sure, whenever you DO lose it, lose it to the RIGHT person. It won't make sense passing all that P, and losing it to someone, eventually having more partners in the long run.
youll need 3. first one for a few minutes, then when u get bored, u take off the condom and go at it raw for a minute or so to see how it feels like, then u put on the next condom and finish. the third condom is just in case the 2nd one falls off.
