The problem with regular condoms
They only cover your dick, and depending on the condom, your dick, etc, they may not cover all of your dick that well.
To really prevent an STD transfer, and they are all a little different, you need to prevent most of the contact we're interested in. For example, herpes is a good example of an STD that you can get from non-penetrative sexual contact. It could be oral, or maybe some stripper / camel-toe slide, before suiting up for the main event.
For those concerned, while a bit fussy and messy, and more expensive, female condoms give a bareback like sensation, and actually do a better job of preventing genital contact during sex.

They were only available at Boots' and they were never plentiful. You would have to check several Boots pharmacies to muster maybe 4 or 5 pieces. Now for the past week I've tried in vain to find any in Pattaya. As usual the pharmacies could tell me nothing except the familiar "no hab". My suggestion they might want to order a load of them as I was prepared to buy in bulk only elicited a grin. A pharmacy placing orders? Ah-ah-ah, another crazy farang scheme!
With so many useless brands of condoms on the shelves it had to be this one that went missing.
It is infuriating to see condom technology remaining stuck in the 1920s. Any howsoever innovative condoms have been hard to get and beset by flaws like ridiculously inadequate lengths or girths. It's like a conspiracy was afoot to force men into unprotected sex.
