In a nutshell - Am in a LDR with dp. Met through OD and have been together four months. We see each other every week and take turns travelling to see each other. He is 38 I am 44. The sex has been amazing and plentiful week in week out and all has been well. However the last two occasions we have made love he has been unable to maintain an erection through penatrative sex - just like that. Seemingly overnight! He apologised and said he is under a lot of work related stress and I was understanding it just seems such a 360 change overnight that it has taken me by surprise. Ive never experienced this before so not sure what if anything I can/should do. We are very happy and in love and tell each other every day/speak/message every day so I feel the relationship is as solid as it can be for the stage we are at . Any advice or experience please? Is it likely to just right itself?
