How about contraception? That's another thing the Christian fundies who infest Ireland have objections to.
A civilised society as we know it is founded on the family. Per Hegel and Engels the most basic economic unit is man and wife and this extrapolates to the wider society via inheritance laws, employment laws, welfare benefits and pensions.
So, you can either choose so-called 'sexual morality' (as per the Bible') or reject it.
Indeed, many gays don't bother with the concept of fidelity. For example, Tom of Finland, who came from a neighbouring parish of mine in Finland, spent most of his youth cruising for lovers, upwards of >800 a year, despite Finland still having harsh anti-homosexual laws right up to 1963, were men prosecuted for homosexual behaviour could be castrated by the state. (This is why he eventually emigrated to California and helped found the Gay movement there.)

It was mainly due to women putting their lives and health at risk by these dangerous methods that legal abortions 'on demand' began to become available.
There is the 'woman's right to choose', but there is also the father in all this.
I knew of a case where a father (unmarried) went all the way to court to try to stop his girlfriend aborting their baby (he lost). If he had been married, or had 'put something on the end of it' - as Jeremy Kyle likes to say - he would not have found himself in that mess.
People have accidents, get raped, get carried away, all sorts of things.
It is said the fall of the Roman Empire, and before that, the Greeks, was because of the dissolution of the family (Roman men often having boyfriends, as well as the wife) and the Greeks also having a love of boys.
