as I've said on other posts I prefer bare but only in monogamous relationships where we've fully discussed and agreed it and after being tested.
my current beau now go bare but that's about 3 months in to a new relationship, and we had a very serious discussion about it and both wanted it and then went and got tested.
He now loves that I cum inside of him and even loves the taste of my spunk, and I love knowing that there is a bit of me in him after we've fucked. Its just more intimate, very sexy, natural and allows for spontaneity in sex.
