You're good. The answer is yes and no. The version coming in the next few weeks has full intercourse for the mc, but not with any of the main story characters (I know, what the fuck...). The most recent version released (0.2.9) has oral, fingerings, massage, and voyeur scenes with the main girls. After this coming release, I'm scheduled to make much smaller and faster updates that will also include a lot more progress with the girls. If you're interested in starting once the sex scenes are more generous, then you should wait until either v0.3 or v0.3.1 (0.3 is a big main story/mechanics update with little sex and 0.3.1 is a sex update with fine-tuning and small improvements to other systems).
