How do you make anal sex comfortable? Obviously use a comdom and Lube and all of that, but is there anything else?
i would guess a lot of foreplay. but im sure some gay guys can help you out more than me lol. cant help but notice it says you are 14.... and the age of consent in the uk is 16 so i would try to wait a little. sex isnt all its cracked up to be, not trying to lecture you but rules are there for a reason!
If you haven't already, practice some safe (aka don't insert any weird shit that's not meant to go up there) anal masturbation so you get used to the sensation.
positions help. You have to find one that works, also enter gently you can't just crack your cock in there, it's going to make the bottom tense up.
