My girlfriend is friends with ALL of her exes, is that reasonable or normal? Plus - I don't like all of them and some of them dislike me. I can tell that some of them have less than flattering things to say about me and I suspect they would like to see me gone from her life? Did you have that problem on Lesbos?
We've said it before, but good advice always bears repeating.
It doesn't matter if you have one vibrator or two. Everyone needs to have that one good friend that knows exactly what to do in case of an emergency.
If something unexpected were to happen to you, they will simply race over to your house, collect up all your sex toys and secretly take them away to where they can't be found.
Your mom will never even know they were there.
