Hey, just my opinion here. I don't personally care what you decide to do with your life or your body. Not that I don't care about you, but its your body and your life.
I lost the love of my life quite suddenly in Louisville, KY in a hotel room with both grandkids in attendance, but I loved him dearly and know that he is probably observing me on occasion where he now is.
My body responds like an 18 yr. old to my husband and he loves it. We have sex for pure pleasure and its carnal, believe me! I've never thought sex for kids was a fair exchange although I do believe heterosexual marriage is the only way to raise healthy kids and is the only God sanctioned way to raise them.
Different strokes for different folks is fine and great. Couldn't agree more.
For me, personally, I have to look at myself in the mirror the morning after and wonder if I have taken part in creation of a venereal disease or a disposable life.
