OK, so we "harp" on the condoms. There are actually
two reasons, one of which is as a "back-up" to contraception other than the Implanon® implant which - dare I say it -
is virtually 100% reliable (except for epileptics). The "pill" is severely limited by the need for the woman to take it reliably, or if she develops a gastro-intestinal illness, and either of these can be a big problem.
The other is - of course - protection from sexually-transmitted diseases (STDs or STIs). If you
really trust that your girlfriend has never had sex with anyone else,
and you honestly know
you have not, then you can perhaps justify unprotected sex. If however
either of these is not the case, then you simply cannot because
most STIs are completely
invisible - you can have them, you can pass them on, and
never be aware of it. In particular I am referring to the viruses that in some cases, albeit only a small proportion, cause cervical cancer in women.
These may represent an exceedingly small risk to heterosexual men, but if you acquire one from one woman (who has in turn acquired it from someone else), and then pass it on to another, perhaps years later (because the fact is, relationships often
do break up), then you
really are not doing her a favour, or anyone else to whom she passes it on in future.
And this is the
very real truth. These diseases
only exist because they are transferred from one person to another during sex. If people only ever had one partner, these diseases (including but not
only HPV - Human Papilloma Virus)
could not and
would not exist. But they
do, and that proves something which impacts on
you as much as anyone else.
Other than that little rant, good work!
