Sir: With regard to your table on sin, it is not the case that pre-marital sex, homosexual practices and masturbation are considered "not harmful" in Buddhism.
Rather, (lay) Buddhists undertake a precept to "abstain from sexual misconduct", which is open to subjective interpretation (which would, of course, be culturally influenced), the key criterion being harmlessness.
