This section is from the book "Human Sexuality", by J. Richardson Parke. Also available from Amazon: Human Sexuality.
When contrary sexuality is perfectly developed, natural union is regarded pretty much as we regard the unnatural. I have a young friend who tells me that he is being - courted at the present writing by a young man and a young girl, the latter of course normal, with equal ardor and pertinacity. These betray the utmost jealousy of each other, the former ridiculing and disparaging the tatter, with even more than feminine vindictiveness; and, without enlightening me as to the possible encouragement afforded the male invert in his sexual advances, he professes extreme embarrassment in his somewhat anomalous position.
To a male invert the idea of natural connection is in the last degree repulsive. Erection with a female is impossible; and no one of those many arts resorted to by women, in coaxing the "balky horse" of sexuality, rubbing, tickling and fondling, will be found effective with the urning; or, if effective, it will only be through the effort of the latter to imagine himself in connection with a male.
In homosexual intercourse the male always feels himself a female, and the female amale; otherwise the inversion is imperfect in degree.
Of course the only means of indulgence between men is by the mouth, by mutual masturbation, by active and passive intercourse inter femora, and pederasty, or intercourse by the rectum. The preparatives of any, or all, of these acts are precisely those of the normal passion, finding expression in kissing, fondling each other, sleeping together and close embraces, in which, when the ejaculation-center is weak, or irritable, the orgasm may occur from purely psychical causes.
