In general, no. I like to see everything. But there are situations where clothing adds to the spice. A quickie works better with clothing as does secret sex in (semi-)public. I like lifting my wife's skirt and just fucking her, when we are walking through the forest. Or her sitting on my lap, riding me with her skirt covering everything, somewhere in nature.
And I like similar situations in porn. When the sex is spontaneous it is more believable that there is no time to remove clothing or that the clothing is necessary for secrecy.
