Venus in Cancer, Mars in Leo: 30 degrees apart, a semi-sextile.
The short answerVenus in Cancer is drawn to warmth and safety. Somebody who feels like somewhere you could put things down. Mars in Leo goes after it with confidence and a certain amount of theatre. The two signs are next door to each other, 30 degrees apart, a semi-sextile, which means the attraction and the pursuit are pulling in different directions.
Venus in Cancer: what you are drawn to
Venus is the placement that answers what attracts you and how you show affection, and it is a far better guide to somebody's love life than their Sun sign. With Venus in Cancer you are drawn to warmth and safety. Somebody who feels like somewhere you could put things down.
You show affection by looking after people, usually before being asked. What you need in order to feel loved is to be let in, and to be needed back, and the thing that reliably puts you off is coolness, and anybody who treats care as clinginess. That last one is worth knowing, because the turn-off is usually more consistent across a lifetime than the attraction.
Mars in Leo: how you go after it
Mars is the other half: how you pursue, how you argue, and what you want physically. With Mars in Leo you chase with confidence and a certain amount of theatre.
You fight proudly, and the injury is usually to the pride rather than the thing itself. What you want is to be wanted visibly, and enthusiastically. And the way it gets stuck is needing the response, and going quiet if it does not come, which is the specific failure mode of this Mars and the thing most worth watching for in yourself.
The angle between them, and why it matters
Cancer and Leo are next door to each other, which is 30 degrees apart, a semi-sextile. This is the part that makes the combination more than two separate placements, and it is the part almost every page about Venus and Mars leaves out.
Two adjacent signs, which share a boundary and almost nothing else. The thing you want and the way you go after it are faintly out of step, in a way that is more irritating than dramatic.
The cost attached: a low-level mismatch you have probably never put into words, because it has never been bad enough to force the issue.

Water and Fire are different elements, so even where the angle is easy there is a genuine difference in material between what you want and how you go about getting it.
What this actually looks like
In practice: somebody drawn to warmth and safety. Somebody who feels like somewhere you could put things down, who pursues with confidence and a certain amount of theatre. Because the two are at odds, there is often a gap between the kind of person you are drawn to and the kind of approach you actually make, and that gap is where most of the trouble lives.
The argument version is worth thinking about separately. You fight proudly, and the injury is usually to the pride rather than the thing itself, and you need to be let in, and to be needed back. Those do not sit together easily, and the usual result is arguments that end without the thing you actually needed having been said.
What to do with it
Check it against your actual history rather than against how you would like to be. Venus and Mars are descriptions of a pattern, and the pattern is in what you have done.
Watch for needing the response, and going quiet if it does not come. That is the specific way this Mars goes wrong and it is the most actionable thing on this page.
Say what you need out loud. Venus in Cancer needs to be let in, and to be needed back, and nobody can supply that by inference.
Stop treating the friction as a flaw. This configuration produces people who are good at relationships precisely because it made them think about it early.
What two placements can and cannot tell youVenus and Mars describe a style, not a person and not a prognosis. They say nothing about whether somebody is kind, whether a relationship will last, or whether you are compatible with anybody in particular. Nothing in astrology has been shown to predict any of that. What this is useful for is recognising a pattern you have been repeating, and a pattern you can name is easier to change than one you cannot.
Where to read next
Venus in Cancer in full and Mars in Leo in full cover each placement on its own. There is no aspect page for a thirty degree separation, because the semi-sextile is a minor aspect with an orb of a degree or two, and two signs being adjacent is not the same as the planets in them being in aspect.
Which houses these two fall in is the part that makes it personal, and that needs a birth time. Here is how to find yours.
