Well in my case I started to use Viagra because I have had bad blood flow for the last 4 years and I'm only 43 now 🤪, always wake up with a "dead arm " getting pins and needles in my leg and told the doc it affects my erection.. I definitely feel insecure about it 😐... My girlfriend of 11 months found my Viagra and lost her shit saying that I obviously don't do it for her and laughed in my face calling me a soft cock C..t 🤔.. and as I'm typing this I realise I should have told her that from the start 🙄.. my bad 😐it was my fault for not being up front and honest 😲😔.. the man is always wrong at the end of the day 🤔🤣🤣😁😘

I can see both sides of this issue. The poor fellow has health issues. He is having to take medicine to correct it.
BUT at the same time,his girlfriend finds the bottle and is like "DAMN, I'm not hot enough to turn him on? he has to take dope to get hard to fuck me? jeez"
I can honestly see where it would make a woman feel inadequate and not up to par for the man she loves.
As for a solution,well all you can do is sit down and tell her you love her and it makes you feel much less of a man because you have to take it but you are trying to be there to fullfill her desires regardless of what it takes to do it.
