Most sensitive signs?

it depends I suppose on what you mean by "sensitive", whether you mean it as in sensitive to others' feelings, or sensitive as in emotional/doesn't take criticism well. I think too often the two are conflated, either way in my personal opinion I think the signs most sensitive to the feelings of others are pisces and cancer, while scorpios are very emotionally perceptive I wouldn't say they're sensitive about it in the sense that they Know how others' feel but they're not the type to pander or work around the feelings of others. I also think leos can be very sensitive to and perceptive of the feelings of those around them, though they're not always the best at expressing it in a way that's palateable to other signs. I think virgo can go between being sensitive in an anxious need-to-please sort of way and being Very Insensitive depending on their own mood.

In terms of the signs sensitive in the sense of being highly emotional, offended easily or sensitive to criticisms I would say leos and at times aries can be very high up there. Cancer is definitely sensitive to criticism y'all take everything personally (alex if u see this ily but u know it's true) but overall much less emotional than people actually give them credit for. Leos, on the other hand, are everything cancers are stereotyped to be when it comes to being emotional I can assure u. Dramatic bitches, all of us. We just enjoy complaining for the catharsis of it ok. On one hand pisces is Very emotional but equally they're so go with the flow I feel like they just get over shit so fast it's weird. blows my mind. I don't know that aries is necessarily emotional but Definitely sensitive to criticisms.
