I have giving other guys head before and they have came but by boyfriend hasn't when I do it to him and I don't really know how to give a hand job? And he always asked me to talk dirty to him but I like to laugh a lot and I can't take it seriously and when I do I don't know what to say and what to call things? can anyone help me? Thanks

You want to talk dirty to him. The beat way to start is to tell him exactually wants going on in you'r head while haveing sex. For example while haveing sex you have diffrrent thoughts going through you'r head. You'r wants and needs. What you want out of sex. Another way is when you have a thought of something naughty then tell him. If you think about naughty sex tell him. Tell him what makes you horny. What you want him to do to you. Just tell him how naughty you can be , show it , feel it.... get into it...
