There have been a few occasions recently where my DP has struggled to maintain an erection. Once it is lost, he can't then get it back and has to come by masturbating himself into my mouth (his penis doesn't really get hard though when he is doing this).
He says that he is tired and this is why he can't sustain an erection.
The problem I've got is I really don't know how to handle this with him. I don't want to make a huge issue out of it but I just feel that I am a hole into which he masturbates. I don't want to make him feel bad so what do I say to him when it happens? Do I just keep telling him not to worry about it and pretending it isn't really happening - hopefully the problem might go away.
