update to previous post : nausea when receiving😔

i (22f)made a post recently about feeling sick randomly when i start to get really turned on with my gf (22f) i talked a bit abt how i hadn’t been touched in some time by her and was eager to be touched more and stuff. she was really receptive and started initiating more which was so lovely to experience but ive now found myself with an unexpected issue. this nauseous feeling when getting really aroused isn’t just when being turned on in general like it has been in prior sexual encounters. i only start to feel really nauseous when im receiving her direct attention or being touched by her, not when im giving or domming at all. now im confused and feel really guilty for some reason and bad because somehow i ended up here after months of yearning for her touch so much i dont get it. i just feel a lot more peace and pleasure touching her at the moment. but i dont know how to be like ‘can i just touch you because i dont feel comfy/secure/sexually safe in my body when you’ve touched me the last few times and i need to work through that (w my therapist)’ without sounding like a total asshole? idk why i tense up and start to feel anxious and so sick and im really struggling to receive now. also now even the thought of touching myself in front of her w or w/o a toy terrifies me and i used to love to do it so much. in some way domming and topping sounds less vulnerable but i literally just said i wanted to be touched more and now i feel like this so im like what tf is my problem? any advice for a better way to word this? how would you react to you’re partner telling you this would you be upset with them? has anyone experienced something similar and been able to ‘fix it’? i feel a bit broken or something
