My boyfriend of 4 1/2 years doesn't want to have sex that often anymore. He says I put a lot of "performance pressue" on him and that this has exaccerbated the issue. For the first few years we had sex almost every day, or every other day. Just 6 months ago HE was complaining that 1-2 times a week wasn't enough.....well now we only spend weekends together and if we're lucky we have sex once during the weekend. I am always the initiator. He says that he has been under a lot of stress at work and other factors and that he is getter older and that all of these things are reasons why. I don't understand that since just 6 months ago he wanted it more. I can't help but think it is because of my recent weight gain (20 pounds in 6 months, 35 pounds gained since we met). I had a hip operation in 2009 and havnt been very active since, also battled with substance abuse but now I am clean and sober...... I am currently watching what I eat and exercise regularly and this seems to be working (I've lost 2.5 pounds in a week). It makes me feel bad that he doesnt want me anymore, I think he could be cheating since we no longer live together but I'm just not sure.
