Friend, my first word of advice would be to calm down.
Please, relax, knowing this one thing:  whatever may "qeunch" your "questionable lust" is available.
You've made the right first step by posting this question in this forum.
Although this is one thing difficult for the young, simply having good command of English will take one far (presumably by "descrete" you mean "discrete").  Always be polite and respectful, and no one to whom you send clear but non-graphic messages will be offended.
Always keep in mind that any explicit request for or offer of anything which could easily be construed as sexually gratifying is, generally, patently illegal and is to be and shall be avoided.
Best wishes,
