short version you will never forget your first one and will never lose that attraction to the first one, simply because he was your first one..

this is just how the brain works. usually the first of anything in life makes a huge impact and strong memories, strong emotions on a person. therefore the brain is primed to remember the "firsts" in life. even something like a childs first tooth, ask any parent if they remember their childs first tooth and the answer is yes. ask any girl if they remember their first period, their first boyfriend, their first date, their first anything and they will usually remember. just because of the emotions and memories tied to their firsts.

how long does it take for you to move on emotionally...well each person is different, some people can move on to the next one relatively easy despite their memories and emotions tied to their first and others it can take years.

one tip is to keep an open mind and not compare the nexts to the first. that way you are open to all the fun and experiences that a new person in your life can bring.

example I could sit here and compare my present love of my life to my first but they would only cause my own heart pain, cause me to miss out on all those things that my love of my life brings to your friendship, relationship, marriage, hopes and dreams.

just take it one step at a time and when you are ready for another love in your life it will happen for you.
