doc - yes i do let them. i would rather they were open, honest and safe about their sex life with some sensible adult input to avoid some of the mistakes i made. i.e. safe sex, good information, honest discussion and a comfortable environment in my home when she 'visits'. i don't encourage it, but i pick up condoms for my son when i get my contraceptive depot every 12 weeks and am closer to both of them as a result. rather that than sneaky shags lords knows where with no protection and adult advice/availability/approachability to talk. i thought i would hate her as she was taking up a lot of my 'baby's' time - but she now visits regularly, stays for meals and sometimes overnight. they aren't doing anything i wasn't at that age (see my posts and do th math), but they are a helluva lot more sensible, open and honest about it...x
