If you go exploring when her mood bar is full, she'll masturbate and empty it out.
If you want to impregnate her the first time through, you'll have to use a ton of saves. Exploring finds lots of unneeded items, so you'll want to save before you start searching, then load that save if you didn't find what you're looking for, and saving whenever you do find an item you want. This is how I was able to micro-manage a single play-through as efficiently as possible.

If you don't successfully impregnate her on a first play through, but you can bring everything that wasn't used to a replay Game+. Unfortunately, the virginity scene is not available on replays. So if you want to just accumulate a bunch of ingredients, just skip through everything and explore with every action. About 2 times through got me enough odds and ends, with a 3rd time to make all the different recipes. Then, I was able to have sex 9 times in 5 days.
If you communicate all 5 times with her, you become her husband and get an extra scene of pregnancy sex at the end.
