Big Brother's hunky runner-up Josh Souza wants to make it clear he is

not an exhibitionist. The 22-year-old student — who spent much of his 88 days in captivity wearing nothing from the waist up — tells TV Guide Online that he, well, just didn't pack much clothing.

"We were in California... it was warm. I said, 'Why dress up every day and wear lots of clothes?," says Souza, who last Friday walked away from the CBS reality show $100,000 richer. "I was just [planning] to jump in the pool and take a shower and lift weights and work out, and that's what I did. So I didn't need lots of clothes, to be honest with you.

"I wasn't going out there to try to say, 'Look at me! Look at me!" he continues. "I was just being myself. But if I came across [as an exhibitionist], so be it; I wasn't aiming for that."

Well, CBS execs were no doubt aroused by the peep show. Although ratings for Big Brother didn't come anywhere near Survivor levels, the show did attract a large number of advertiser-friendly female teens — many of whom were lured by Souza's hot bod. But sorry girls, the stud muffin soon may be spoken for. The aspiring actor/model reveals that the flirtation between him and housemate Brittany could spill over into the real world.

"We got the chance to talk very briefly after I got out, and everything was good," he says. "We just hit it off really well in the house and got along great. [But] if there's potential [for a romance], I'll have to find out."

When asked if being cooped up in the compound with television cameras everywhere was frustrating from a sexual point of view, he replies, "Hell, yeah. You're in there for three months and you know you can't do anything! It's funny, you could do some things; it never just seemed like the right thing in the house to happen. So, yeah, you can't wait to get home and have some fun."
