Arivera, I'm like you... I don't talk about it! My parents and I have sort of an unspoken "don't ask/don't tell" policy. I'm sure they know we DTD, and I'm sure they know FI and I stay over at each other's apartments... but we don't talk about
it, and FI and I aren't moving in together until the wedding.
My sister let FI and I stay together in her guest room, but we don't talk dirty details at all. She understands where I'm coming from since we were raised to feel like all sex was taboo and must not be spoken of... we can roll our eyes about
that together.
I don't have friends, so nobody else to talk to about it. :P
