yes some antidepressants and cardiac medications can interfere with sexual activity so please discuss this openly with your doctor since i do not know what meds are you are taking. the size of your penis should not be drastically changing no more than your hands or feet getting smaller. it may seem that way if you are having erectile problems. this is another common male disorder that may be able to be rectified but any use of ed meds will need to be prescribed by your doctor -- someone who knows your medical history the medications you are taking and can examine you.
