My mate says that it's no problem for her, but, still, I'm a little uncomfortable wearing these things in her presence. Honestly, different women view things different ways. Personally, I tend to like women who are playful and adventurous enough to enjoy such things. If your wife fits that bill, count yourself lucky and have a good time.
Many wives find such things quite confusing, and some are positively revolted.
Helps break down barriers. Don't worry, you'll get over it. However, don't take you wife's acceptance for granted. Take her at her word, but don't ignore any hints she might give you to any discomfort she might feel. Only she can tell you that.
