I wouldn't worry about it, it doesn't likely mean anything about you in the terms of sexuality; very often the different people that appear in dreams represent different aspects of yourself, marrying someone rarely means the exact same thing as marrying someone in waking life - marrying means joining two things together; it's more than likely that this character represents a certain aspect of yourself that your subconscious would like you to become closer to. Perhaps this sounds a bit confusing?

I don't know anything about Strawberry Shortcake; but say for insrtance that you think of that character as funny, something to laugh at; it could mean that you need to be more in touch with your funny, jokey self and take stuff less seriously. It depends what Strawberry Shortcake means to you?
