More a question then a confession

I'm a 21 year old female and I've been married to my husband for 2 years now (together 4). In the last 20 months hes become less interested in sex. Going from weekly to 2- 3 months and now its been 6 months. I've tried walking round the house naked and with very little on and tried to interest him but only says he's not interested and when we have done it (beforehand) he tells me he can't "come".

Is this likely or should I be worried he's banging someone else and if so what signs should I be looking for?
