Hey girlfriend , it a good thing you like giving head to your husband, you are already tasting him,,those clear liquid lubrication juices that are coming out of his penis , well if you are okay with the taste at that point just let him cum, but you dictate the amount and depth of his penis. Suck on it and when he gets there just let it in and if you dont' like it just back off and finish him with your hand. It's an acquired taste ,,just try it, my wife loves to give head but won't let me cum in her mouth and I respect that. That is what girlfriends are for ,,,lol,,,,take care.
