Yes, I know I need to move out my parents house asap. I don't like living here, I would prefer my own place.

However, I have to deal with the situation I have right now. I've got a date with a girl and I'm finding it hard to find a time when we are both free and I can conveniently give a good excuse to my parents. Here are the problems I face:

1) I've been told daytime dates are a disaster because she will just see you as "one of her friends/colleagues", so I want to go on the date in the evening.

2) I don't have any friends (this needs to change, I know). So giving the excuse "I'm going out with friends" will not work. It will look way too suspicious.

3) I go to 2 social groups a week. One on Thursday evening, one on Tuesday evening. I always go at set, rigid times and return at exactly the same time every day. If I stay overnight for instance (eg. if we were to have sex), that would look massively suspicious.

4) I asked the girl and she already said she's busy every Thursday evening.

5) I never do anything on Fridays or weekends, so again it will look really odd and suspicious if I went somewhere on those days.

Of course I could just tell them honestly "mum, dad, I have a date with a girl and I might have sex with her" but who would ever do that? That would be so incredibly awkward, I want to avoid that.

Realistically, what excuse can I give?
