cash78mere if he was really your first you didn't
need to get tested (obviously STDs can be transmitted without penetrative intercourse); though you nevertheless took the tests, as a gesture.
I think that if he does have an STD with many he wouldn't even know about it.
You'd know about it though, if you caught it and later couldn't concieve because chlamydia or PID had made you infertile. Or "worse" STDs than those.
Remind Mr cash78mere that his special penis isn't immune to every STD on the planet
contrary to what he seems to think; and in today's climate being ready to have sex requires being ready to deal with the responsibilities which come with it like testing.
Sexual activeness isn't
just about ecstasy (no drug reference intended) and he needs to (re-)learn that.
