Salam - I want affection but freeze when it happens

Salam, Sisters, I could really use some advice because this is getting to me. I don’t think I dislike physical touch. Actually, I appreciate it, even in non-romantic settings. Things like holding hands between spouses, respectful handshakes, hugs with family, or gentle, appropriate displays of warmth all sound comforting to me. I want that kind of halal closeness. But when it actually happens or when I try to start it (which is already hard for me), I just freeze. My body locks up. I get so stiff that the other person notices and then they hesitate to try again. It feels awkward and it upsets me. It’s not like I grew up in an abusive home or totally deprived of touch. My immediate family weren’t very physical, though my extended family showed more affection. I do value personal space, but I don’t want only distance either. When I get a hug or any touch, I tell myself to relax and I feel mentally safe, but my body doesn’t follow. My mind goes blank, I tense up, and it feels like it’ll never stop. People sometimes joke about it or comment, which just makes me more self-conscious. I don’t know why I react this way or how to change it. Has anyone else gone through something similar? Is this anxiety, an emotional block, or something else? How can I slowly become more comfortable with halal, appropriate affection without freezing? I hate being seen as the unaffectionate one when I’m loved so much 😭 - I want and enjoy affection too. My facial expressions also give me away and make it harder. Lately I’ve noticed friends and family being so natural and effortless with touch, and it makes me wish I could be like that. Any tips for small steps, duas, or things to try that fit within our values would be really appreciated.
