Its me again

Lol its me again! Well things are getting better in the bed I guess… I still cant last long but make her orgasm before we start having sex so I guess thats good… But I really want to last longer when ever I drink and we do it I can last for a long time I know its because of drinking but I feel that I should be able to control it since its still me that going for a lot longer… Another thing is I got condoms that are supposed to make you last longer problem is it makes it really way to numb and I cant stay hard lol im such a dork… My girlfriend is so cool about it though thats why im so concerned… Any ideas?… I heard masturbating to much makes you more sensitive should I not do that any more? I just really care about her thats why I am so worried…thanks!
