Most scholars believe that Shakespeare’s sonnets were written for friends and distributed privately at first.  When they were published, they were not published in order.  For this reason, this sonnet’s title does not hold a signifance for Shakespeare.   It is love poem where the young man tries to convince the young lady to have sex with him, and in that sense the title is significant because it indicates that it falls in line with Shakespeare’s other sonnets.  Shakespeare did not give the sonnets titles, but the absence of a title does not necessarily mean anything since none of these sonnets had titles.
