aekel not sure how old you are but I find I take longer now to cum than when I was younger (now in my 40’s). This can be advantageous but it can also be disadvantageous (especially if you have a lazy woman who just wants you to come and then fall asleep)
I’m the same as whitechocolate in that BJ’s won’t make me cum and wearing a condom well, forget it…totally desensitizing.
Don’t know the solution for you. I usually find not cumming for a while helps but that’s boring!
