Of course they are OK! Unless, of course, the object of one’s desire does not want those things. Then it is not OK.

The “OK-ness” of any action hinges on clear consent – if you have it, go forth and be merry. If not, then stop.

In other words, is not the action itself that defines whether X or Y is OK or not – it is whether or not the two (or more) people involved fully consent to it.
