Want to get her some skimpy lingerie, a book on sex, or a sex toy for Valentine’s Day? If you’re not sure, my suggestion is to not do it. If sex is an area of contention in your marriage, I really suggest you not do it.
If you still think it’s a good plan, this page has some shopping links that should be clean, and I have finally moved Buying lingerie without dying of embarrassment onto this site. If you are looking for a first toy, I suggest a simple egg or bullet vibe – not threatening, and actually very useful.
