It is entirely a womans decision...never let a guy pressure you into swallowing if its not what ur into. Men don't realise that they taste different every time and some tastes vary from pleasing..to absolutely revolting depending on what they have eaten throughout the day. With me it all depends on my mood..sometimes i spit...sometimes i swallow..either way i still make sure its enjoyable as possible for my partner.
But a hint for the ultimate tasting blowjob....get ur partner to drink half a pint of pineapple juice about 30 mins beforehand and it tastes exaclty the same..very pleasing
