Hi dominu. At first glance I thought I saw my chart. We have the Sun and the Ascendant on the exact same degree.
Correct me if I'm wrong, but you said
others you meet find you cold, not you yourself. I've heard it a lot too (I have Moon in Capricorn semi-square Pluto) but by people who don't know me well or when I was in a state of emotional turmoil. I've even been described as rigid, an ice queen, a shy girl, the calmest person alive, but I'm none of the above.
Coming to my point... How do your friends/family/partner perceive you? Is it just the people that don't know you very well or is it even the ones closest to you that see you in this way?
Personally, looking at your chart, I don't think you're cold at all. You said it yourself it doesn't seem so to you, so maybe it's them. I'd say you're anything but cold. Emotionally rich and powerful, I guess dramatic too, with some heavy undertones but don't let that scare you. I do suggest diving into the depths of the Scorpio waters, I think you carry much secrets inside, that even you don't consciously know of. I feel that with awareness comes empowerment.
Maybe dig into the lives of your parents/grandparents. Pluto in the 8th house is said to have some mayor heritage of Scorpio themed emotional patterns. And being conjunct your Moon makes it a big part of your emotional self.
Maybe you
feel something lurking but don't
know what it might be or where it came from. I digress...
If
you feel you would want to be more open but don't know how to I'd suggest engaging your Leo Venus in everyday life and your relationships.

If you want to, I'd propose you read the whole thing, you may find some other commonalities.
Best,
