I am currently with a girlfriend that is much healthier for me and I have a stronger connection with. Our sex life is not as creative or developed as my past ones. My inner critic leaves me with thoughts that that we are boring and that that is what matters. But I could never do that again because she will think I am a creep.
What really matters is what you currently enjoy - do you enjoy what you currently do? If so that is enough … comparing with others including your own past may not be all that helpful - so perhaps go lightly in yourself and try to focus on the current experience.
It sounds as though you are managing to have some really helpful thoughts about your situation. Sex is part of our relationships but having healthy and happy relationships is also important. It might be that you will be able to have some ‘healthy helpful’ conversations when you feel ready. I am sure if you can do this in a constructive way - you might find that you will have a very full and fulfilling relationship and I am sure your partner will be pleased that you are able to communicate about this important aspect of your relationship. Good luck : )
