Like a lot of introverts these days, I've resorted to internet dating. I took the initiative and messaged a guy I thought was completely hot, and to my surprise, he actually responded, giving me kudos for taking the initiative. After a week of messaging, we had a date. He seemed very enthusiastic and wanted to see me again. So enthusiastic, in fact, he wanted to have sex and made that clear by asking me a lot of questions about my experience, personal preferences, etc. Which was fine by me because I don't have too many hangups about sex. So we got together again a few days later at his place and had pretty great sex and then...... oy. I guess about three hours of a lot of silence followed. We played two games of chess while he watched Sports Center and then we played Rock Band until 1am. Then he drove me home. I texted him half an hour after he dropped me off and told him I hoped we could get together again, and he seemed enthusiastic in his agreement.
Here's the problem. I'm an INTP, he's an ISTP. He's 32, I'm 25. He's crazy accomplished---doctor, marathon runner, in a band, speaks three languages, and is mind-blowingly hot. I'm no slouch, and I have plenty of my own hobbies and am quite athletic. But I feel like I can't possibly measure up to him and am not good enough. I completely clam up around him and don't know what to say, even though I'm pretty witty and verbose when typing. He says he's had problems dating in the past because women become "too attached" to him, and he can't commit. I didn't think that would be a problem for me, but because I'm hyper-analytical, I'm tearing my hair out trying to figure out if he's actually interested in me or if I'm just the flavor of the month. I try not to bug him, so I send him maybe a text message a day, and if he's online I say hi. He responds very quickly, but doesn't have a lot to say. And his job as a doctor has him keeping very irregular hours.
I'm completely stumped as to how to show him I'm interested without freaking him out, and I'm lost as to how to figure out whether he's interested in me. Bleh, any advice?
