Passion in dating/marriage after 30?

I'm a 32 year old man who's been single for an undiscolsedly long (like really long) period who's about to enter the dating market again. This hiatus was entirely my own doing because I was busy with bettering myself (education, exercise). Also, I was in the military for a long time and I was too busy working/deployed and also seeking God in that time.

My concern is that dating at my age will be more transactional, as in we both need to hurry up and get married and have children. That's actually want I want, but I feel like something will be missing. I see young couples at my church and I can see how in love they are and the way they look at each other. Like Isaac sporting with Rebecca, like Song of Soloman. I want us both to be infatuated with each other the way younger couples are. I feel like I've missed out on that now that I'm "old." I want fire and passion (checked until marriage of course).

Time is passing me by and I just keep getting older and realizing this more every day. I need reassurance that my future love life won't be too mature or stale, that is if it ever exists at all.
