<human>: Can you give me the gist of the text in a nutshell?

Maybe you can help me gain some perspective. I've been in a relationship for seven years and got married a little over a year ago. During high school we had a lot of sex, like usually twice or three times a week. Understandably, when we moved in together for year five, the sex became less frequent. I'm under the impression that this is pretty common. Once we became married, our weekly romps became even more rare. Now we only have sex about two times a month but I still maintain the same sex drive that I've had as a teenager. I feel that because of this, I've gained wieght and now a lower self esteem. 

Now about three or four times a year my friends and I partake of MDMA. During our last Ecstasy trip my brother (my husband's brother whom I'm really close to) joined us and shared a little too much information with me (a common side effect). He is only 19 but has never dated, kissed, or had sex. He's still young so I've never put too much thought into it until he told me that it's his intention to never marry, have children or be with any woman. He expressed his desire to be the"40-year-old virgin" which got me to thinking. I don't think he's gay because our family is pretty understanding and supportive so there is no reason he should feel the need to hide that from us.  I'm beginning to believe that they might be refusing sex because of a childhood trauma they both experienced when they were growing up. What should I do. I think I'm going to stay out of my brother's business but the information he shared with me has me concerned not only for him but for my husband as well. We've shared everything together and I know he's had a hard life growing up. I'm thinking that it's had more of an effect on him than he's let on. Should I suggest therapy? How would I do that?
<bot>: My husband and brother seem reluctant to have much of a sex life, I'm wondering if they suffered from something traumatic during childhood and should seek therapy.
