After I feel her body go limp I slow down and try to force myself to orgasm - it doesn't always work and half the time she wants me to stop before I can get there. So to answer your question, I would say I reach orgasm 7 out of 10 times. When W decides to please me, sex doesn't usually last as long. Somtimes these eposodes are quickies but usually she likes to tease me crazy first with foreplay which takes time. So, overall, she also reaches orgasm 7 of 10 times.
Age does have an effect.
When I was younger I would reach orgasm at the thought of having sex. I would even have multiples in one session. This no longer happens. I am also more sensitive to masturbation. I have to be careful now because it takes the better part of a day for me to enjoy intercourse after I do it myself or have been helped by W. Good thing for anonimity.
