When I was at church when I was younger, I would feel bad because I kept having sexual thoughts about Jesus and Mary. I was very devout at that time and loved them very strongly. I felt so guilty over it. But now I don't think there's any reason to be guilty about it. After all, the mystics have written very beautiful erotic things about their deities - Christian mystics especially. Just look at the Song of Solomon, which is erotic poetry and can be viewed as being between God and the Church. Wanting to be married to Christ and Him be the ultimate lover of their souls, etc. I think this is a very natural thing. After all, making love is one of the best ways to express your love, devotion and passion for someone. So why feel ashamed? The ecstasies of Saints and mystics of various religions sound like amazing orgasms and are even presented very similarly in art.
