Zero sex drive

Hi I’m 6 weeks and 4 days right now. My partner has been great, gives me foot rubs, gets me whatever I need or desire. When he goes to touch me or kiss me though I feel nauseous. He’s a good looking guy and since telling him, he’s kept on top of his hygiene and grooming, it’s just the thought of being physical with him makes me sick. What should I do? Is it ok to feel this way? I don’t like hurting his feelings but I also don’t want to do something I don’t want to do. Is anyone having similar issues? Thanks
