<human>: Can you summarize the given text in a few sentences?

Hi all.  I'm (F25), he's (M26), in relationship for a little over a year.

I'll start off by saying that I'm his first girlfriend.  I'm pretty much his first everything, which I found out about six months into the relationship.  He was scared to tell me but ever since then, I feel a lot closer and special to him.

Lately, I've noticed that my boyfriend's been dropping a bunch of hints about marriage.  For example, I was sick last week and in bed with nothing to do so he bought me a bunch of magazines, one of which was a bridal magazine.  Another example, he was looking through my jewelry box the other day and said, "Hmmm... You have a lot of rings.  Do you even wear these?  What's your ring size?"  (He was trying to be sneaky.. hehehe).

So last night, I finally asked him if he was looking to get married someday and he replied, "Yes, if I was married to you."  

I only have one concern though, a concern that I didn't share with him last night.  What if he decides a few years from now that he wants to experience other women?  Since I'm his first love, I'm terrified that his feelings for me may be temporary.  Has anyone been through this?
<bot>: If we get married someday, will he want other women?  I'm his first love and I'm terrified he'll want to experience other women someday.
