I'm curious too, but I think 2.5 hrs BJ would be a way too much and boring
Everyone is different, but in my experience the longer any kind of sex
lasts - whether HJ, BJ, BLS + jerking myself, or intercourse - the better
it feels. I think that might apply to nothing but kissing & cuddling too.
{BTW i find the best kind of massage/HJ is when i am masterbatng and
the lady is working with her hands on my balls, prostrate and bum areas.}
Sometimes after a while of HJ, BLS, or BJ i get a desire for intercourse.
Not that i'm getting bored, but feel i'd enjoy even more a full body
contact sport. I guess it's because it's closer, more intimate, you can
kiss & feel every part of the lady's soft body.
If i am ready to cum anytime i want to before intercourse, due to
a time of preping {for maybe 30 or 60 minutes} with something,
such as a BBBJ, then it makes it so that i don't have to work very
hard or long when i am pumping her to get to that same point of
ecstasy {i.e. being able to cum}. And to maintain that level of
pleasure.
But going straight to intercourse does not usually feel as good as start-
ing out with something else like BLS while i jerk, or the 3 handed massage
mentioned above. But after a while of these things i can enjoy intercourse
to the same degree as the pre game warmup activities.
