I've voted yes, but it depends on how you define " screaming "
Not that I'm yelling at the top of my lungs, but I do make noise if the place/etablissement allows me to.
Making noise has many positive effects as
1. You're letting the girl know you're cumming, so normally she would put in some extra effort
and provide a grand finale
2. If she doesn't want you to cum yet, she'll stop & teases you some more. That makes me even more horny, which is fine by me.
3. If you're like me, like to CIM, then it's just polite to let her know you're almost there as she can prepare herself and hopefully put in some extra sucking
The only times when I had to be mute was when I was young & still banging girls at their parental homes
or in public ofcourse.
I dissagree with Pakka's opinion: " I don't think girls say anything before they cum.....that only happens in porn! "
While that might be true for WG's, most of the girlfriends I had, if not yelling, at least made it clear to me they were cumming. Why? Well probably the same as my point 1&2.
Though I must say that my gwai mui girlfriends were much more open about it then their asian counterparts. Like some said, some of these were really grabbing me and telling me to fuck their brains out. Aah, those were the times ...
I usually don't believe WG's are cumming while I bang them, but I'll just go along when they fake it.
