Sounds to me, based on some of your other questions, you are a bit young to be having sex. Say she gives you a BJ but she has cold sores (which may be invisible) and you catch genital herpes. What are you going to do? Are you man enough to go to the doctor for a diagnosis and can you afford a prescription for the antivirals? Or are you going to come back here whining about what you can do now? What if the condoms breaks or slips off and she gets pregnant? Are you man enough to support her and what ever she decides regarding the fate of the child?
It is good you are asking questions, but you seem to be thinking only about yourself and your own physical pleasure. Please stop and consider the consequences.
hi. My boyfriend had the same problem. It happened after he came the first time that day. We (attempted) sex for the second time but when he put the condom on, he lost his erection. This happens to everyone. I know it is annoying, but you are not weird. After about the 4th time having sex ever, he could recharge alot more, but there is a stopping point. Try to relax, it may be stagefright. If it happens all the time, you might see your doc.
