Hey all 
For my Latin class, i’m going to be teaching my class about present subjunctives, BUT, while i know how they’re used for wishes (ie with “utinam”), i’ve been looking though my textbooks for examples, and while i can identify them (although they’re nowhere near as common as past subjunctives), i can’t pinpoint in what exact situation there’d be used. I know that the imperfect and pluperfect subjunctives are used with “cum”, but is that still the case for a present subjunctive? Only then there’d be the problem of having to start the sentence “When…” and then adding a present, when to me it only makes sense to use a past, or possibly future, verb in this situation… am i missing something really obvious? 
Thank you to anyone who can help
Any good textbook or grammar should discuss these extensively.

Cum doesn’t have to mean “when”, it can mean “because” too. So:
Cum te amem (pres. subj.), laetus sum.
“Because I love, I am happy”.
That makes sense right?
And in indirect questions and statements the subjunctive is used, so:
Scio spintria sis.
“I know that you are gay”.
Scio spintria sis.
“I know that you are gay”.
Really? I thought it was always accusative and infinitive?
Oh, maybe it is. Heh. But this is correct, right:
Scio quid facias.
Maybe you’re right, always acc.+inf. in sentences like that one.
Scio te spintriam esse, then.
Interesting choice of example. Been reading Suetonius’ life of Tiberius?
No, but I guess I should then.
Indeed an interesting rendition, but I’m not sure “gay” is a synonym for “male prostitute”.
So that’s the actual meaning of spintria? My dictionary says “homosexual man”.
