That’s assuming that there’ a big gap between him and the Mane Six. Helps that the older they are, the less relevant any gap you do see between them becomes.

At most, the Mane Six are young adults, and Spike is more than a child, or have you ignored all the times Spike has been mature than responsible? Also, Spike and a member of the Mane Six having sex is no where near bestiality. That’s like saying that a human and a Twi’lek getting kinky is bestiality.
Also, they’re all fictional creatures so it doesn’t really matter if they have sex. The age thing is definitely a problem though. not that I like any Spike shipping, and especially with the Mane Six
