<s>[INST] Me and my girlfriend have had sex Atleast 5 days a week for last couple of months . Recently I have had a problem staying hard , and being able to ejaculate. Also, by the second round im able to stay hard but I m dmaller and takes way longer to ejaculate. [/INST] Hello, What you are experiencing is a normal physiological phenomenon and nothing to worry about this. As you are having sex 5 days in a week definitely the amount of semen production will be less that doesn't mean your sexual desire has come down. When ever you are trying for the second round of sex normally ejaculation will be delayed due to the sympathetic activity. As per the history you are not having any problem with regard to your sexual activity. Thank you. </s>
