Hi everyone!

Me (23NB) and my partner (23M) of 5 years are considering nonmonogamy but our situation is a little... delicate.

I have diagnosed PTSD and my relationship with sex is, safe to say, fraught. It's led to me not being able to meet my partner's needs for sexual contact. So, to help him take the pressure off me, he suggested we open the relationship. We would have strict guidelines and he would only have hookups with no intention of "adding or subtracting" (his words) anyone to the relationship.

I worry though, that because of my existing insecurities surrounding our relationship and sex, that I would only get more upset when the intention was for me to commit fully to my healing journey. I worry that I'd be holding him back and he'd grow to resent me if I say no to this, which opens up a whole other can of worms in regards to the longevity of our relationship.

I have spoken to my therapist about this, and as my partner also has some mental health hurdles, it would be a prerequisite for him to also be in therapy so he has someone unbiased he can discuss his sexual life with.

I'm still unsure where I stand on everything, and would love to hear if anyone has any firsthand experience with situations like this, or any general advice. Thank you in advance! :)
