i have a 12 1/2 yr old son who is growing up really fast...he is a very clever lad in top classes in all his lessons theres just one problem where i a iv always allowed him to be honest and open with me (as i believe this is the relationship i want with all my children) he is now getting into gurls (only fancying mind) and is starting to want to discuss sexual issues that are being raised with friends in school...i am only 29 i had him quite young and tho i dont mind discussing important sex issues there are certain things im not willing to discuss yet until hes older (oral sex etc) how do i let him know this without actually making him think he cannot talk to me full stop...i like to know what hes up2 and dont want him to think he cannot talk and discuss things with me...i just dont think he needs to know certain things as its way to soon...
