How old would you say is okay to have ?

Physically and mentally you are at tender age. Wait till you are 18 and ready to mingle. At this age your all organs are not fully developed and as such it is not proper to indulge in at this age. You will really enjoy more and there will be no cause for you to regret later on if you lose your virginity at the ripe age and when you are fully aware of all the consequences and ready for the act of love making with the Mr. Right.
