sounds like you are doing a wonderful job. i have all girls myself, so not real sure how to handle a boy at this age, but with my girls i have found myself in some similarly awkward situations, like when my middle girl at age 10, with her 7 and 17 year old sisters there, how men have sex. she had the basics of what went where, but having only seen a baby boy having his diaper changed to go by she wanted to know the mechanics. boy that was scarey, especially with big sis snickering in the back seat lol.

all you can do is answer as honestly and openly as possible. reassure that you will always do so and that is ok for him to ask. and be thankful that he loves and trusts you enough to come to you with these questions. also might not hurt to have dad broach the subject with him to see if maybe that would be more comfortable for your son. hope this helps.
