Please help me!

I feel so anxious right now. Please help me feel more sane and okay!

I asked my boyfriend if we could fulfill a sexual fantasy of mine. Which is to have fan-fiction or do sexual text roll play together. He is totally down to do it and has said he’ll figuring out a night this week that will work well for us to do it.

The problem here, is it’s not something he’s ever thought of or fantasized about. So I just am feeling right now that I’m selfish and being sexually/emotionally needy.

Can you please tell me that I don’t need to feel this way? He’s agreed and said he’s interested to try it... that means he doesn’t think I’m being selfish. Right?

Having previously been in a long relationship where I was emotionally and sexually abused, it’s so hard sometimes to feel comfortable and okay with having wants.

Am I okay? Was I okay to ask my current boyfriend to do this with me?
