One more thing. To trigger the gate 1 secret sex scene, you need to "fail" clawjob twice and blowjob once then click a few times on the static part to have Gomamon try and "rape" you in your sleep
For the second secret scene, "fail" each sexual activity once and click on the idle screen again until Gomamon has an existential crisis and comfort him.
Make sure to "fail" all 4 sex options and talk thoroughly so you can digitize his Nurse outfit and find out about the crests. Make sure that before the last firewall that you click on the idle screen after giving him the outfit that way you get the whole confession of love scene. It's the best way for him to Warp Digivolve
