I only took one intro to Psychology course at university, had trouble staying awake, but here is a Psychology course that actually sounds interesting. Perhaps you could become a sex therapist.
PSYC 3P34
Psychology of Human Sexuality
Introduction to the psychological study of human sexuality. Psychological methods, along with developmental, social/personality, cognitive, and neuropsychological approaches are applied to different issues in human sexuality, including sexual differentiation, gender identity and sexual orientation, attraction and love, patterns of sexual behaviour, sexual dysfunctions, sex differences in sexual behaviour, erotica and pornography, sexual coercion and paraphilias, and sexually transmitted diseases.
