My partner M41 and I F39 have been together 3 years. I seem to have a higher sex drive than him. He struggles to maintain an erection. Sex is good when it happens, which isn't very often. He has tried porn with and without me with very little success. We most often have oral. My partner is currently having tests from the GP and has been given Viagra, which works but even with that he struggles to cum when we have PIV. We share our time between our two homes until he moves in with me when his lease is up.
Recently my SD6 stayed with us and as I need work doing on my home to make room for her she stayed in our large room on a spare bed at the other side. My partner had a huge erection when we were cuddling in bed (no meds taken) and we hadn't been intimate for around a week. So he asked me to pleasure him as SD was sound asleep so I did. SD couldn't see our bed and he was quiet and he came extremely quick, quicker than he has ever came before. He said he thinks it was rushed due to SD being over the other side of the room and it was quiet, as I can be vocal and love dirty talk.
Not sure if this is relevant but he is overweight. I have over the last 2 years lost alot of weight and still have a way to go to get to target. He works a week on a week off with the occasional couple of days overtime. He doesn't smoke, but does drink every now and then.
What can I do to improve our sex life, its frustrating, I ask him fantasies, his is me in lingere which I do.
