You are not dead, it was your partner that has now gone. You are still alive and so are your normal feelings and urges, it would be unusual if those feelings returned the following day, but, who is to say that would be wrong, there is no "laid down" time scale for any part of that period that follows the loss of a loved one.
This is not the question that we would, or could, ask to our friends and families, so, as in most case's, we keep it to ourselves, only to further confuse our minds.
Lets presume that you have met this person. You have got to know him/her, and you were happy with the comforting cuddles that you shared on meeting or leaving their company. The cuddles become more often and get a little tighter, their hands hold you a little tighter and your faces are closer. Cheek to cheek is only an inch or two from lips to lips. now you feel different.
Sexual feelings are aroused, and, you break away, because, you ask yourself, is this right?, am I being unfaithful?, is it too soon?. Good questions, and probably at the right time.
Nature has programmed our bodies to have sexual feelings for the continuance of life, so, it's doing its job, but, a sexual relationship is also a show of love, and, a pleasurable thing.
Is it love, or, is it something else. There is no act that can bring you any closer to that other person . Is it the thought of simply being held, and, holding that is on your mind?, or, is it love?.
You, and, only you , can make your next decision. Your mind is already filled with the thoughts about, unfaithful/right/too soon, maybe that is also one of natures programs, Maybe this is a thinking time, and don't worry, you will make the right decision.
I haven't answered the question "How soon to have sex after loss of a loved one?", I can't answer the question. There isn't one simple answer to the question.
