The first thing that jumped out at me when I was reading your question was that in regards to kink - blindfolds, restraints, and gags - you say that you’re not into it.
Sometimes we do things because our partners enjoy them. That’s not always a bad thing. Knowing about a desire that our partner has can create enthusiastic willingness on our part to participate. If that’s how you feel about kink, great.
However, if you’re doing it to please your partner in a way that doesn’t feel awesome to you, I encourage you to take a break from the kink aspects of your sex life. Take some time to examine what you want and enjoy for yourself. Then, renegotiate with your partner around what activities you’ll engage in together.
When it comes to getting over trauma, that’s a lot trickier and it can take time - especially when engaging in activities that trigger panic. Please be gentle with yourself and know that you’re not on anyone's schedule but your own when it comes to taking time to heal.
For more specific advice, I reached out to my colleague Angie Gunn, a licensed clinical social worker who specializes in sexual trauma. Here’s what she had to say:
"This is a really complex question because, based on the limited information provided, it sounds like the sexual assault experiences have had a significant impact on you. This can be categorized as a trauma experience, something which overwhelms your system's ability to cope. When trauma happens, your body alters its response system to mobilize against a threat, triggering hyperarousal (fight or flight) or dissociation (freeze or float). However, those responses can persist, even once the threat has subsided. Engaging in an act that is reflective of the original trauma (ie: sex) can be a particularly strong cue for that response system. From what you've shared, it sounds like at times you seek high sensory input, lots of sexual activity, as a method of managing the hyperarousal response. Additionally, you've continued to explore restraints and the use of bondage in sex. The panic you're experiencing seems to indicate a rejection of the use of sex as coping, bringing awareness to an area of sensitivity and uncertainty following the trauma experience.
