"I hope all you ladies going on about STDs and condoms use them too. You know, just in case one of these sirens come along and force your partner to cheat on you against his will."
What a ridiculous comment!
For one thing any person that cheats isn't being forced to do so. That's an active decision they have made.
In my own case the second I suspected (correctly) that my ex was cheating I stopped sleeping with him altogether and got a full sti check.
In all my relationships with men bar the first where we were both virgins (and believe me it was painfully obvious he was too) I've used condoms throughout excepting after we both had clear sti screening and we were ttc.
As someone of the generation who had it drummed into me by the media, teachers, parents etc about safer sex due to the AIDS scare and has nursed patients with full blown AIDS, HIV and advanced forms of other sti's (if untreated they can still turn very nasty) I'm very aware of the risks and act accordingly.
It shocks me that there seems now to be a much more lax attitude to these issues. Yes there's good treatments for Hiv and other sti's but they don't necessarily work for everyone and there can be seriously harmful side effects.
So I act accordingly and take care of my sexual health.
