You can never win in these threads. If you say a low number, you're told you're being too harsh on yourself or seen as fishing, and if you put a high number you either have to make it obvious you're joking or risk looking like someone with their head so far up their own arse they can't see their own face anyway.
Also, what number someone gives themselves says a lot more about their self-perception vs. how attractive they actually are.
As of now, I'd say a 7.5. Though with a better sleeping routine and an intense 6 month workout routine to add muscle and complement my naturally broad shoulders, I think I could realistically be an 8.7.
