My partner has problems with maintaining an erection and with a previous partner he had problems even becoming aroused. He was prescribed Viagra but when it didn't work it was decided that it was a mental block and perhaps worsened by medications. We have tried numerous things including different types of Cock Rings and have finally found something that helps Durex Pleasure Ring. Perhaps if you and your partner are open to bedroom aides you may also find something that will help while he addresses his issues; you can also buy lubricants that are supposed to increase sensation etc they may also help him feel more. Good luck with it but just remember sex is only part of a loving relationship there are other ways to express and show love
