Been in a relationship for 30 years plus. We are both almost 50. I'd say for approximately 6 months now my partner is having trouble with maintaining an erection during sex. We've talked about it and he bought some viagra from the pharmacist but tbh it doesn't really make much difference. He's already got massive self esteem issues and I'm so scared of bringing it up again that I'll make the problem worse as it will be on his mind more. Basically almost every time we have sex he has a semi so it obviously doesn't feel great like it should. He does pleasure me in other ways but I miss having normal piv sex. How an earth do I say that without it destroying his confidence?
