The only sexual acts that are wrong are the ones that hurt or exploit another person without his or her agreeing to it in a mature way and ones which are used as a substitute for developing real self-esteem and independence.
There is nothing wrong with a woman having a baby and having no intention of having a man around as long as she has plenty of male relations and friends to befriend her baby.
It is not true that contraception makes the man see the woman as a sex object for all agree that sex when conception is eliminated or very unlikely is loving and moral. Women must have the same freedom as men to explore their sexuality. It is not true that the contracepting person sees the baby as a burden for anti-contracepting people see the baby as something to be avoided when they try to reduce the chances of conception for nobody thinks sex is more about babies than anything else.
It is thought that having sex is promising to care for and be with the person you have it with forever for it is giving yourself to another. To have sex with somebody you do not care for is to give your body but not yourself for you are holding back your heart and that is contradictory and obviously abnormal and demeaning. It is obvious that it is better for sex to express love of some kind. When you give a person yourself you are certainly promising to be there for them forever. However, you do not have to be their friend forever but you do have to be there if they have nobody in an emergency.
Nobody must feel pressured into having casual sex. It is a sign of strength and wisdom to say no when one isn't interested. Those who think otherwise don't matter. The fewer sex partners anyone has the better for it is healthier. Sex can become a substitute for love and all deserve better.
Only bigots condemn homosexuality. It is condemned on the grounds that it is unnatural. That is based on the lie that what is natural is necessarily good and what is unnatural is bad. It is a lie for everybody can see that nature is cruel and we all can and should defy it when we have operations. Nature has strange ways so it could be natural for persons to be attracted to the same sex for many heterosexual men do not like full intercourse as much as they like other acts. Laying down laws like such and such a sex act being unnatural is foolish and narrow and conceited for everybody's tastes differ. When nature makes it possible to be gay and for it to do no harm then how can it be unnatural? Even if many homosexuals abuse their sexuality that does not make homosexuality itself bad for it is the abuse that is bad.
It is wrong to sexually molest children and the immature even if they consent for they are not meant for such activity and if they were loved for themselves and not for the kind of bodies they have the person who desires them would wait. Sex abuse is not wrong just because it may have bad results but because the person should not be treated like a thing. We do have to treat persons as things to avoid treating far more that way. But this condition does not occur in sex-abuse. We should let our wrath burn fierce against child-abuse.
