To me it honestly doesn't matter since I am a swallower. As a general rule though it is polite to let your partner know, especially if she isnt a swallower or it is your first time with a new partner. That way she has knows and has a chance to decide.
I like to know, especially if I'm giving head I can prepare myself, and def. during sex.It makes things more intense for me.
Let's put it this way: When I am about to cum during sex, there is no way she cannot know it because I usually change my thrusting depth and rate and I start to groan a deep, primal growl that leaves no question that I am about to explode!:dgrin
Well, I can tell when my husband is about to come in my mouth, so he really doesn't need to tell me. He slows his thrust, and gets rock rock hard, and his head swells. Of course I can HEAR him when he is cumming. Of course I cannot tell so much physically during sex, but I LOOOOVE to hear him tell me he is cumming. It's just plain hot to hear him getting off. Don't do full blown handjobs, sorry!
i only liked to be warned during a head job. im not much of a swallower. or a catcher for that matter. i find his cum very thick. and im just not a thick taste kind of girl. lol
I always ask, i mean if it's the first time or one of the first times of doing something with them. Because odds are i dont know them well enough lol.
