Ok, so me and my girlfriend have been together about 2 months now and we’ve been getting a bit physical lately. We haven’t had sex, but we have been messing around. Recently she’s been going down on me and I find it very hard to last longer than like 30 seconds at most. I’m not sure why this is. I’ve had 2 other girls go down on me in the past (not at the same time, lol) and with the first girl I had to force myself to get off and with the second girl I couldn’t even et off at all. Usually before she does it we’re dry humping for a while, prob 30 min to an hour. During this I can keep myself from finishing, but sometimes it’s hard just because she’s pretty vocal and it turns me on even more. I’ll get her off at least one time by doing this in combination with rubbing and what not. What I’m concerned about is why can’t I last when she does it? I like her way more than the other girls that did it, is it just because she’s better, which would be weird because I’m the first one she’s done it to?
