Hey I got some questions, ignore any or all.. and some suggestions of course.

One having to overcome my Catholic upbringing and moral views that were imposed on me do to this. From one of your previous post it sounds like you have had number of partners. You had sex... but werent allowed to enjoy it?

sex there was majorly different
how so.

if it is only the warmth that makes it easier then his mouth is just as warm or warmer and also wet. there are also a couple of lubes out that feel warm when rubbed on the body. KY is one, its at the drugstore.
just speculation but Im guessing it is the mental stim your get from knowing of his climax that 'moves you along quicker'.

Keep experimenting.. you are married... no moral excuses left.
Two or three times a evening on a regular basis put your H out of the average , but they arent multiple O's, he still has a refractory period. Sorry, just being technical.

As for the golden showers, inside you is definitely unhealthy, but I have had a few instances where the girl lost bladder control. Crazy things happen during sex, they make for funny stories and good memories.
It all comes out in the wash, so if you are both enjoying the activity, different strokes for different folks.
