Help! 😞

I've been with my SO for almost 3 years now and love him to death. We recently got engaged, but I'm scared to marry him because of the difference in our sex drives.. he's fine with where we are at, (the sex is great when it happens) but it's not often enough for me. I've taken into account our busy schedules and how hard he works. I've also talked to him several times about planning out specific time, tried dressing sexy, looked up tips... I plan to talk to him again, but wanted someone else's opinion on the situation. 😵
