the point about masturbation, certain sects of christianity, such as catholicism, officially oppose masturbation as it is a waste of sperm. that is a very loose way of putting it, but other than a sign of lack of respect for your body (this is how the bible sees it, not everyone:P) which is suposed to be in itself 'a temple of god', those sperm are all potential children!
sex: christianity officially states that the 'oint' of sex is to produce children, and that this can only be allowed to happen between two people joined in holy matrimony in the name of god. there is also spiritual bonding between the two people, but i was always lead to understand that the bible teaches that a man and a woman come together in that way to produce children, for it is the will of god ('go forth and multiply' etc...)
If god's real how come he didn't see that coming?
he gave people free choice, he isnt a cruel merciless dictator, that would kind of go against...well everything!
It's descriminatory to preach abstinance because that means that gays could never have sex.
your point makes no sense... if you preached abstinence as a way of life for everyone then nobody could ever have sex...not just gays... if you say, 'wait until you are married' then many churches allow gay marriages, abstinence does not apply extra-strongly to gay couples, that's a bit...weird o.O
Intercourse is defined as the interaction of male and female genitalia.
I'm pretty sure that is sex.
yes, that is sex, so is oral sex, which involves only one of the two, as is anal sex (that'll probably be starred out, but it's the other one either gay male or straight couples can do, begins with a...yea, you get it) still sex, intercourse is one of the many varieties of sex
disclaimer: i am not strongly religious myself, but i've had a thorough secondary religious education, focused largely on christianity, and if i contradict myself a few times, that is only natural, showing different sides
