Nope, I don't think so. Anybody I was with usually never had much of a problem telling their family and friends about me.
As for me, my conscience will always win over and I care a lot about my family to ever keep something like that a secret. If there is somebody in my life, I will want to let them know about it, my family cares to a great degree about me and I know they worry a lot, so being open with them and letting them into many aspects of my private life feels wonderful.
I admit, I've been afraid to talk to my parents in the past because everybody around me seemed to have issues trying to tell their family about the person in their lives, and usually have to scheme in order to find their way around spending a life with them; completely disregarding the feelings of those that have been with them and cared for them as they grew up.
I didn't want to be that sort of person, I love my family too much to ever let anything like that happen, that is why...my parents know that I have a boyfriend and any I've had in the past, I talk to them about things that happen between us and even tell them a lot about him. Not only does it boost their trust of my boyfriend, but it also makes them more certain that I'm being straight, and not downright secretive.
