Me (31M) and gf (28F) of 4 years have pretty consistent 1-2 nights of sex a week. The sex is usually pretty normal or average for use 10-15min, lots of time with her riding cowgirl as she prefers that. I have a pretty stressful job and also tend to work long hours and 6-7 days a week, which has driven my libido down. I have never been a repeat orgasm guy so we usually get her started long before me and use toys to aid in making sure she finishes. Or we use toys during sex which we both enjoy. But she has expressed that she would like to try to go multiple times, our initial efforts havent been great. After I cum I am usually 0% horny anymore and have like a mental switch. Any tips or tricks or hell old fashioned remedies? I know its probably mostly mental and we are working on that.
