Thx bros tamtom and james.tanz. Yup indeed, it's becos I came across some of the FL that offer AJ that's why recently hav been thinking abt it.
Main reason i'm worried it will hurt the gal is that altho my didi is not very long it is quite thick when he's standing. So I dunno if it'll be safe for the gal. Think in the end have work up my courage to try it once very slowly and see if it can fit.
btw, is it very addictive? will you want to go back to normal FJ after trying it?
sorry for my nooby questions, kamsia
