The attraction for these two could be passionate and instantaneous. Leos need of constant attention could cause a lot of trouble with the naturally undemonstrative Arian whose "me first" attitude directly rivals Leos own. Leos need of constant flattery may meet with disapproval and resentment as Aries believes that once said is enough for anybody.
The trick is for neither to take the other all that seriously. It's an excellent sexual match, for both are passionate and romantic. They also share the same likes and dislikes in other areas of life. Aries is optimistic and open to life; Leo is generous and good-hearted.
Between the two of them, if one is loving and sensitive with the other, meeting that persons emotional needs, there will be a happy union that will last for a lifetime.
