Yes, but they probably don't lose it until they are like 60 yrs. old.

Men do lose their sex drive. Why do you think there is such a demand for Viagra and other male enhancements? It can happen at different times. 28 seems a bit young. He might check with a doctor to be certain there are no other physical problems.

it is possible as many things affect our sex drives. it may be something totally unrelated to your relationship. stress at work, financial concerns, and even medical issues can affect sex drives. there is always a period in a relationship that is a down cycle, you may just be in that. you may want to find a way to spark things up a bit in the bedroom, just to see where that may lead.

well i guess he could but most don't lose it till about 60 then it just slows to about once a week. later on maybe once a month. maybe he hasn't lost it just using it some place else. like in any relationship keeping the fire going takes some work and doing different things. maybe he is tired of the rut or is on drugs or is starting to like his guy friends better. well like i said it takes both working at it to keep things going and it takes open commutation about things too. so if you want email and i can try and give you some ideas to try if you want.
